Lasagna is a little labor intensive...
The quick and easy ways to make it pale in comparison to the complicated (and $$$) ones.
It would be a disservice to you to suggest anything besides a real one.
But here goes anyway...
Cheap and easy lasagna
1+ lb ground beef
1 small onion, diced small
3 cloves garlic, minced
1 jar (32 oz) thick spaghetti sauce
1 1/2 cups water
2 eggs
1 tub ricotta cheese, about 1 lb
1 lb mozzrella, set aside a little for the top, about 1 cup
1/2 cup grated Parmesan, set aside a little for the top, about 2 Tbs
salt and pepper
8-12 oz uncooked lasagna noodle
9"x13"x2" minimum pan size
Fry the beef with the onion, garlic and a dash of salt and pepper.
Stir in sauce and 1 cup water and set aside.
If it's really oily, drain most of it off before you add the sauce,
but put a couple Tbs in the 9x13 pan first.
Mix the eggs, cheese (except for a cup of mozzarella, and a good sprinkle of the Parmesan), 1/2 cup water in a bowl.
Preheat oven to 350 F.
Start layering the pan with sauce, then noodle (say three or four of them) then cheese mix,
and repeat.
Cover with foil, bake for about 50-60 min.
Carefully remove foil and add remaining cheese.
Bake about 10 min. more, and let it cool a little before cutting.
I'll post a better one later, i'm getting hungry...
