You can make a simple calzone using the store bought pizza dough that comes in cans. Spread the dough out on a cookie sheet evenly. Layer the ingredients of your choice in the center of the dough, and top with sauce and cheese. Fold the narrow end of the dough toward the center on each side first, then fold the long edges toward the center and carefully pinch securely closed. Carefully flip the entire piece over so that the seam is on the bottom, then place in the oven and bake according to the directions on the can the dough came in.
