I’m Lindsey — registered dietitian, mom, and reformed meal prep hater.
Yep, hater. For years I dreaded meal prep. It seemed unnecessarily time-consuming. I didn’t want to spend half my weekend making perfectly portioned identical meals that I would dread eating by Wednesday. I dreaded even the thought of the same boring chicken, broccoli, and rice in a bowl every. single. day. (after day, after day…)
If that’s been your experience with meal prep, too, I want you to know two things:
- You’re not bad at meal prep.
- There’s a much easier way to do it.
This post is the full breakdown of how I actually meal prep every week — the system I call Prep Once, Think Less. It takes me about an hour on Sundays, it doesn’t lock me into eating the same meal on repeat, and it’s the single biggest reason my family eats more protein, fiber, and plants without me thinking about food all week long or having to spend copious amounts of time in the kitchen every night.
Let’s get into it.
The Prep Once, Think Less Philosophy
Before we get into the how, I want to share the why — because the method makes more sense when you understand the thinking behind it.
Prep Once, Think Less is built on five principles. They’re not rules. They’re the mindset shifts that make the whole thing actually work.
- Realistic beats perfect.
A prep that happens always beats a perfect prep that doesn’t. You don’t need a color-coded fridge or a four-hour Sunday. You need something doable enough that you actually do it — this week and next week and the week after that. - A little prep goes a long way.
You don’t have to prep everything to feel the difference. Washing fruit, cooking one protein, making a batch of rice — small efforts at the right time create sizable relief throughout the week. - Ready beats motivated.
You will not always feel like cooking on a Tuesday night. That’s not a character flaw — that’s real life. The goal of Sunday prep is to make healthy eating the easy choice, so you don’t have to rely on motivation you won’t always have. - Simple food is still good food.
A bowl of rice, chicken, and roasted peppers is a real meal. It doesn’t need to be complicated to be nourishing, satisfying, or worth eating. Simple is the whole point. - Convenience is a tool.
Using a rotisserie chicken, buying pre-washed salad greens, or grabbing a protein shake on a hard day isn’t cheating — it’s smart. Convenience exists to support your life, not replace your effort. Use it without apology.
Why Most Meal Prep Doesn’t Stick
Here’s the thing nobody tells you: the version of meal prep you see all over the internet — seven perfectly portioned containers in a row — is the hardest version of meal prep. It asks you to:
- Decide on Sunday exactly what you’ll want to eat on Thursday (it reminds me of my daughter’s preschool teacher asking her what she wanted to be when she grows up, and she said, “how am I supposed to know that now?!”)
- Cook complete meals for hours
- Eat the same thing over and over until you’re sick of it
So when you “fall off” by Wednesday, it’s not a willpower problem. The system was rigid, and real life isn’t. Your week changes. Your cravings change. Some nights you have 30 minutes to cook and some nights you have 30 seconds.
A meal prep system only works if it bends with your week instead of breaking.
The Prep Once, Think Less Method: Prep Components, Not Containers
Instead of prepping complete meals, I prep components — building blocks I can mix and match into whatever meals my week actually needs.
Every Sunday, I prep some combination of these five things:
1. A Protein
One or two proteins, cooked and ready to grab. Think slow cooker salsa chicken, a batch of baked chicken, browned ground turkey, or a dozen hard boiled eggs. Protein is the component that makes every other meal decision easier — and when it’s already cooked, dinner is 80% done.
2. A Carb or Grain
A pot of rice, quinoa, pasta, or roasted potatoes. One batch, endless directions: bowls, salads, sides, “stuff on rice” nights.
3. Washed and Cut Produce
This one sounds almost too simple, but it’s the component that changes everything. Fruit that’s washed and ready gets eaten. Peppers that are already sliced end up in lunches. Produce you have to wash and chop at 5:47 PM on a Tuesday? That produce dies in the crisper drawer. We’ve all been there (yes, even this dietitian!)
4. Grab-and-Go Snacks
A few snacks that are portioned and ready to grab when hunger hits — peanut butter yogurt dip with apple slices, cottage cheese ranch dip with veggies, cheese and crackers, trail mix. I aim for snacks with protein or protein + fiber, because those are the ones that actually keep you full.
5. One or Two Ready-to-Eat Meals
This is the only “complete” food I prep — usually a breakfast like high protein overnight oats or egg bites, or a lunch like cowboy caviar pasta salad that I can grab-and-go on a couple days. One or two, not seven. And that, my friends, is the sweet spot between “Sunday took my whole day” and “I have nothing ready.”
That’s it. That’s the whole method.
Why Components Work When Containers Don’t
When you prep components, you’re not deciding your meals on Sunday — you’re just making every future meal decision faster. Tuesday night, you open the fridge and assemble: salsa chicken + rice + peppers + a little cheese = burrito bowls in five minutes. Wednesday it’s the same chicken over greens with whatever produce is left. Thursday, pasta night with that ground turkey.
Same components, totally different meals. Nothing gets boring, nothing gets wasted, and nobody’s eating room-temperature broccoli out of obligation.
And here’s the honest part: my Sunday prep doesn’t cover every single meal of the week, and it’s not supposed to. It’s a kick start. It takes the 21-meals-a-week mental load and shrinks it down to something manageable. Prep once, think less — not prep once, never cook again.

What This Looks Like in a Real Week
So you can see it in action, here’s a typical Sunday prep from my actual kitchen (I share these every week in my weekly meal prep roundups):
- Protein: juicy baked thin sliced chicken + hard boiled eggs
- Carb: a big pot of rice (often it’s my bone broth rice for another easy protein boost!)
- Produce: washed berries and grapes, sliced cucumbers and bell peppers, a veggie box for snacking
- Snacks: cottage cheese ranch dip, energy balls (my kids beg for my monster cookie protein balls on repeat!)
- Ready-to-eat: a batch of protein overnight oats for breakfasts (they’re so versatile! A fan-fav and a fam-fav, too!)
Total time: about an hour, including cleanup. And most of that hour, the oven is doing the work while I prep produce.
From that one hour, my week gets burrito bowls, chicken salads, snack plates, grab-and-go breakfasts, and at least one “I cannot cook tonight” dinner that comes together in minutes anyway.

How to Start This Week (without prepping all five)
If you’re brand new to meal prep, do not start with all five components. Start with two:
- One protein
- Washed and cut produce
That’s it. Those two components alone will make your week noticeably easier, and easy is what makes you come back next Sunday. Add a grain the week after. Build from there.
The goal isn’t a picture-perfect fridge. The goal is opening that fridge on a busy Tuesday and feeling relief instead of dread.

Prep Once, Think Less FAQ
How long does meal prep last in the fridge?
Most cooked proteins and grains are best within 3–4 days, per USDA guidance, which is exactly why I prep a kick start, not a full week. I front-load the early week with prepped components and keep the back half flexible. Produce varies — berries are best eaten earlier in the week, while heartier produce like carrots, peppers, and snap peas easily lasts the week.
Do I need special containers?
Nope – and that’s kind of the point. Since you’re not portioning out complete meals, regular food storage containers and a few jars are all I use. Glass containers are nice because you can see what’s inside (food you can see is food you’ll eat), but use what you have.
How long does it take?
About an hour for me, but my very first preps took longer — that’s normal. Lean on hands-off cooking methods: the slow cooker, the oven, a pot of eggs on the stove. Your job is mostly washing, chopping, and letting appliances do their thing.
What if my family won’t eat ‘meal prep food’?
Mine wouldn’t either — that’s why I don’t make “meal prep food.” I prep ingredients, and we build meals my family already loves. The kids’ tacos and my burrito bowl come from the same components. Everyone makes it theirs.
Is this enough protein and fiber?
That’s the quiet genius of components: when a cooked protein, a grain, and ready-to-eat produce are the easiest things in your fridge, your meals naturally land higher in protein and fiber without tracking anything. If you want a head start on fiber-rich options, my high fiber foods chart is a great place to begin.
Your Turn!
That’s the whole method — no rigid containers, no eating the same lunch five days in a row, no Sunday spent entirely in the kitchen. Prep a few components, mix and match all week, take what you need, and make it yours.
