Unroll pizza crust, stretching into a 14x11-inch rectangle. Spread Ricotta cheese on half of the dough lengthwise to within 1-inch of edge. Sprinkle pepperoni, ham and Mozzarella cheese. Fold unfilled side of dough over filled half and press edges together. Transfer to greased baking sheet. Bake at 400 degrees for 20-25 minutes. Sprinkle with basil and Parmesan cheese, if desired. Slice, serve with marinara sauce for dipping.
