Roll out the pizza dough and cut it into squares. Place mozzarella, pepperoni, Parmesan, garlic powder, and oregano in the center of each square. Fold the dough over the filling and pinch to seal.
Brush the tops with olive oil and place on a baking sheet. Bake for 15 minutes or until golden brown.
Serve warm with marinara sauce for dipping.
Notes
For extra flavor, you can add more spices or herbs to the filling.
