Preheat the oven to 375°F (190°C).

Roll out the pizza dough on a floured surface.

Cut the dough into squares.

In a mixing bowl, combine mozzarella, pepperoni, parmesan, and Italian seasoning.

Place a spoonful of filling on each square of dough.

Fold the dough over to create pockets and seal the edges.

Brush the tops with the egg wash.

Place the pockets on a baking sheet.

Bake for 20 minutes or until golden brown.
