Roll out your chosen dough on a lightly floured surface to about ¼ inch thick.

In a mixing bowl, combine the mozzarella cheese with marinara sauce and any additional toppings.

Cut the dough into squares, about 4 inches per side, and place a generous spoonful of the filling in the center of each square. Fold the dough over to form triangles or rectangles, then pinch and seal the edges.

Whisk an egg in a small bowl and use a pastry brush to coat the tops of each pocket.

Preheat your oven to 375°F (190°C). Arrange the pizza pockets on a baking sheet and bake for about 15 minutes until golden brown.

Allow the pizza pockets to cool for a few minutes before serving them warm with extra marinara sauce on the side.
