I use two boxes of Mac & Cheese, and a full jar of spaghetti sauce to make this. I think the ratio turns out better. Flavor the spagetti sauce before hand to your liking or it will be too bland. And make sure you prepare the Mac&Cheese by the lite directions as the recipe recommends or it won't turn out right. Not as good as real lasagna, but close, and a lot easier. Quick, cheap, and a favorite amongst picky eaters.
