3-Third Step: Layer the fillings Layer the browned sausage over the bun bottoms in the baking dish. Add 3/4 cup pizza sauce on top to keep everything moist without making the buns soggy. Then, sprinkle on 1 diced green pepper, 2/3 cup sliced mushrooms, and 2/3 cup sliced black olives for that supreme vibe.

4-Fourth Step: Add cheese and top buns Finish with 1 1/2 cups of shredded Monterey Jack cheese, then place the top halves of the buns over everything. This cheesy layer is what makes these sliders irresistible!

5-Fifth Step: Prepare the buttery topping Mix 1/2 cup melted butter with 2 teaspoons Italian seasoning, 1 teaspoon garlic powder, 1/2 teaspoon red pepper flakes, and 1 1/2 tablespoons Parmesan cheese. Brush this over the buns for an extra flavor boost.
