OK. I don't have a specific recipe for this, but it works well.
2 jars of spaghetti sauce
4 oz Lasagna noodles
2 8 oz packages of shredded mozzerella cheese
1 12?oz container of ricotta cheese - not the smallest one they have, but next one up... Heck, just get whatever and put it in, the more the merrier
So you just layer everything anyway you want. This is what I do:
Mix all the ricotta with all the mozzeralla, add some salt and pepper if you'd like.
Put one of the jars of sauce in the bottom, a layer of uncooked (that's the nice part about this recipe) pasta, half the cheese mixture, a layer of pasta, another jar of sauce, another layer of pasta, then the rest of the cheese.
I think I put it on High for around 3-4 hours, but I'm sure it'd work on low for maybe 6-8 or so. Nothing magical to it, it's just that you have to cook it long enough for the pasta to cook and then it's done! I love lasagna, but I never make it b/c I'd have to cook the pasta, THEN make the dish. But if you do it this way you just throw a bunch of stuff together and leave.
