Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

Roll out your pizza dough on a lightly floured surface to about 1/4-inch thickness and cut into 6-inch squares.

Mix your choice of fillings in a bowl, season with salt and pepper, balancing cheese and savory ingredients.

Spoon filling onto one half of the dough, fold it over, and crimp edges to seal.

Whisk the egg and water, and brush the tops of each pocket with the mixture.

Arrange the pockets on the baking sheet and bake for 15-20 minutes until golden brown.

Cool on a wire rack for a few minutes before serving with marinara or your favorite dipping sauce.
