This is the best lasagna recipe! It is now a staple for my family, as I am gluten-free. The zucchini works perfect as a replacement for noodles. Because i'm not a vegitarian I add the meat of 4 sausages to the sauce and a full 28 oz can of San Marzano tomatoes. The sausages from Costco are amazing! The cottage cheese (I use pressed cottage cheese)and parmesan mixture is so tasty. I never would have thought to use cottage cheese - I was actually going to substitute it with ricotta when i first made the recipe, but I'm glad I stuck to the original ingredients. My whole family wants this recipe now.. they love it so much. Oh, and it's also low-carb friendly. My husband is on a strict Atkins diet and though there may be a higher carb count because of the cheese and tomatoes he makes an exception! It's a keeper!
