This isn't exactly like a lasagna since there aren't any pasta noodles. Instead of the pasta, there are layers of zucchini and cucumber. I accidently peeled a cucumber the first time I tried making a zucchini lasagna and ended up with this which tasted pretty good to me. You can make the whole thing out of just zucchini if you want. I use Fat Free Organic Spaghetti Sauce with Mushrooms from Trader Joe's.
