Unroll one pizza crust, stretching gently to make a 14-in. x 11-in. rectangle. Spread half of the ricotta on half of the dough lengthwise, to within 1 in. of the edges. Sprinkle with half of the pepperoni, ham and mozzarella. Fold unfilled side of dough over filled half and press edges together firmly to seal. Transfer to a greased baking sheet. Repeat with remaining crust and filling ingredients. Bake at 400° for 20-25 minutes or until golden brown. Sprinkle with Parmesan and basil if desired. Slice into serving-size pieces. Serve with spaghetti sauce.
