Prepare pizza dough. Divide into four sections and bring to room temperature.
In a medium bowl, stir together ricotta, parsley, basil, parmesan, black pepper, and ½ cup of grated mozzarella. Stir to combine fully.
Use your fingers or a rolling pin to flatten each section of dough into an 8-9” round.
Place ¼ of the ricotta mixture in the center of the round. Add additional toppings - sausage, diced tomatoes, and additional mozzarella cheese.
Fold one side of the dough over to form a half moon. Pinch and roll the sides of the dough to enclose the toppings completely.
Whisk together the egg with a tablespoon of water. Brush the egg mixture over the calzone to add a golden sheen to the baked calzone. Cut a couple slits in the top of the calzone for steam to escape.
Bake calzones on a baking sheet for 20-25 minutes or until deep golden brown.
Brush tops with a bit of olive oil and sprinkle with additional parmesan cheese and fresh herbs.
Serve with marinara sauce.
Notes
Storage: Refrigerate in an airtight container for 3-4 days. You can also free prepared calzones. Bring to room temperature and bake according to instructions.Be sure the calzone dough is not rolled too thin or it may break while folding and pinching the edges.The egg wash makes a beautiful golden sheen on the baked calzones. It’s not necessary. You could also brush with olive oil or sprinkle with cheese/herbs before baking.Use any pizza toppings that you’d like.
