If you're making the pizza sauce and the mock-ricotta, do that before starting the instructions for the pizza pockets.
Preheat oven to 425°F. Place parchment paper on your work surface the size of your baking sheet.
On parchment, roll pizza dough very thin. Divide into four portions.
Leaving a 1-inch gap around all edges, off center, on one side of each piece spread 1 tablespoon pizza sauce.
Add 2 tablespoons Mock-Ricotta, a generous ¼ cup mozzarella and some pepperoni.
In a small bowl, beat the egg with a teaspoon water to make egg wash. Brush outer edges of dough with egg wash.
Fold the empty half of the dough over filling and press to seal. Fold the edges of the dough over and pinch to further seal the dough.
Brush the tops of the calzones with egg wash and sprinkle each with parmesan.
Cut a few small slits in the top of the calzones to release steam.
Slide the parchment onto the baking sheet. Bake for 15 minutes or until golden brown.
Serve immediately or cool completely, wrap individually and freeze up to 3 months. Reheat in the microwave or in the oven.
