Use a microplane to zest the orange. Be careful to not zest any of the white pith, as this is very bitter.
1/2 teaspoon orange zest
Slice orange and juice it.
1 naval orange
Add the juice, zest, yogurt, and protein powder to a small container and whisk together. Add chia seeds and whisk again.
1/2 cup Greek yogurt, 1 scoop vanilla protein powder, 2 tablespoons chia seeds
Seal container and store in the fridge at least four hours, or until the chia seeds have absorbed the liquid and you're left with a thick, pudding-like texture.
Top with orange segments, vanilla Greek yogurt, whipped cream, or any desired toppings, serve, and enjoy!
