Preheat the oven to 375°F (190°C).

Roll out the pizza dough on a floured surface.

Cut the dough into squares or circles.

Place a spoonful of pizza sauce, mozzarella cheese, and pepperoni in the center of each piece of dough.

Fold the dough over to create pockets and seal the edges with a fork.

Place the pockets on a baking sheet lined with parchment paper.

Bake in the preheated oven for 15-20 minutes or until golden brown.

Remove from the oven and let cool slightly before serving.
