Preheat Oven:
Set oven to 375°F. Line a baking sheet with parchment paper or grease lightly.

Prepare Dough:
Roll out pizza dough on a floured surface to about ¼ inch thick. Cut into 3×3-inch squares.

Add Fillings:
Add a spoonful of sauce in the center of each square. Top with mozzarella and a few pepperoni slices or other toppings.

Form Rolls:
Fold each square into a roll, pinching edges to seal. Brush seams with beaten egg.

Coat with Doritos:
Crush Doritos into fine crumbs. Roll each pizza roll in the crumbs, pressing to coat.

Bake:
Place rolls on baking sheet. Spray lightly with cooking spray or drizzle with olive oil. Bake 12–15 minutes until golden and crispy.

Serve:
Cool slightly before serving. Serve warm with extra pizza sauce for dipping if desired.
