Preheat oven to 300°F and lightly grease a 9x13" baking pan (or any baking dish that accomodates the size of the slider buns).
Carefully slice the slider buns in half and place the bottom half into the prepared pan.
12 savory butter roll slider rolls
Layer the bottom buns with shredded chicken, then pesto, then shredded mozzarella, then provolone. Top with the top half of the buns and set aside.
2 cups cooked chicken, 1/2 cup pesto, 1/2 cup shredded mozzarella, 4 slices provolone cheese
In a separate small bowl, combine the melted butter, garlic, and Italian seasoning. Carefully brush this garlic butter on top of the buns.
1 tablespoon butter, 2 teaspoons garlic, 1 teaspoon Italian seasoning
Bake for 10 minutes covered with foil, then bake another 10-15 minutes uncovered. (If they're getting too brown, but the foil back over the sliders.) The sliders are done when the cheese has melted.
Slice along the bun lines with a serrated knife. Serve warm and enjoy.
