Cook lasagna noodles until tender, using directions on package.

Mix egg with Ricotta cheese.

Preheat oven to 350°F. (moderate).

In a 7- by 12- by 2-inch baking dish, spread layers of one-fourth of tomato-meat sauce, then three noodles, and another one-fourth of tomato-meat sauce. Top with half of each kind of cheese. Add another one-fourth of the tomato-meat sauce; then the remaining Ricotta mixture and Mozzarella cheese. Spread with remaining noodles and sauce. Top with remaining Parmesan cheese.

Bake, uncovered, 30 minutes. Cool 10 minutes before serving.

NOTE: Lasagna freezes well either before or after baking. Thaw in refrigerator. Leftover lasagna can also be stored in the refrigerator for a day or two, and tastes just as good reheated as when freshly baked.
