Cook noodles following directions on package; drain, rinse in cold water and separate. In a buttered 3-quart baking dish make two layers of the noodles, meat sauce, ricotta, slices of Mozzarella cheese and Parmesan cheese, in this order, using about half of each for each layer. Bake in 350 F oven 30 minutes or until bubbly. Serves 6 to 7. Pepperoni may be added to meat sauce if desired. You may double the recipe for sauce; use half in making the lasagne, as above, and serve the remainder, cooked down until quite thick, in a sauce boat along with the lasagne.
