Preheat oven to 450 degrees F. Set pizza stone in oven to get hot while oven preheats (or use a baking sheet turned upside down).
Divide pizza dough into 8 portions. Roll a piece into a flat disk, about 1/4 inch thick. Add about ¼ cup of toppings to one side, including a generous sprinkle of cheese. Fold the other half of dough over the toppings and seal the edges together.
Place calzones on a large piece of parchment paper.
Use a sharp knife to make a slit on top of each calzone (for steam to escape while baking). Lightly brush tops of calzones with beaten egg, then sprinkle with a little parmesan cheese and Italian seasoning.
Transfer calzones (on the parchment paper) to the hot pizza stone or baking sheet in the oven.
Bake for 12-14 minutes or until golden brown. Allow to cool for at least 10 minutes before serving. Serve with warmed pizza sauce, for dipping.
