For calzones, divide the dough into 4 equal portions and form into 4 balls. Place on a lightly oiled baking sheet and cover with a damp towel. Let rest for 15 minutes, then transfer to a lightly floured surface and roll out into 4 (10-inch) circles. Place filling of choice in the center of 1 side of each circle, then fold dough over filling to meet edges of filled side. Crimp edges with a fork or your fingers, then cut a small slit in the top of the calzone to allow steam to escape while cooking. Cook on a preheated pizza stone or backs of cookie sheets in a preheated 475 degree F oven for about 10 to 12 minutes, or until well-browned. Remove from the oven with a metal peel or spatula and serve immediately.
