Preheat oven to 500 degrees. Prepare baking surface by dusting lightly with flour or cornmeal.
If using homemade pizza dough, follow dough directions up until shaping. Divide into 4 balls and make (4) 8"-10"circles.
Place ingredients on one side of each circle. Divide seasonings evenly and sprinkle over each. Fold the top over each and crimp the edges by pinching and folding over. Optional: cut 2-3 small slits on the top to prevent bubbles.
Place on prepared surface and bake for 10-12 minutes (watch to make sure the tops don't burn).
Remove from oven when golden brown. Brush with butter and sprinkle with parmesan. Cool for 3-5 minutes before serving.
Notes
-This recipe makes 4 large calzones and 6 medium size calzones. It just depends on how you divide the dough.
