Preheat oven to 350° F
When the dough has risen, turn onto a floured board. To make 8 individual calzone, divide the dough into eight equal balls. With a rolling pin, roll into 4-inch circles. Add a spoonful of filling onto the center of each calzone.
Fold over to form a half-moon and pinch the edges to seal. Using the end of a fork, press around the edge to make sure seal is tight.
Cover a pizza or baking pan with cornmeal or parchment paper to prevent sticking. Place your calzone on the pan. Using a shart knife, make two slits through the top of the dough to let out the steam while baking. Spoon 1-2 tbsp. tomato sauce over the top and sprinkle with mozzarella cheese.
Bake at 350° F for 45 minutes until cooked through and golden brown.
Remove and place on a serving platter and enjoy right away. If you have any leftovers (probably not!), calzones will keep in a covered containter in the fridge for 3 days.
