Here's the recipe we used! (It's my aunt Myrna's.)
1-8oz. box lasagna noodles (we used whole wheat...a little better for you and you can't even tell a difference)
2 pkgs. spaghetti sauce mix
12 oz. can tomato paste
2 lbs. hamburger, cooked, drained, and seasoned
Combine sauce and hamburger. Simmer while noodles cook. Drain noodles in cold water.
16 oz. mozzarella cheese
Parmesan cheese
Grease a 9x13 pan.
Layer:
1. noodles
2. hamburger sauce
3. parmesan cheese
4. mozzarella
Top: Sauce and mozzarella cheese. Bake at 350 degrees for 30 minutes and let stand for 15 minutes to set.
