My "lasagna"

1-2 boxes rotini pasta
16 oz. container cottage cheese
16 oz. shredded mozzarella
1 jar spaghetti sauce
Boil noodles in salted water. Drain noodles when they are al dente. In a 9x13 pan layer noodles, sauce, cottage cheese, and lastly mozzarella then repeat until you have a nice full pan. (Usually 2-3 layers.) Make sure there is a lot of cheese on top. Bake at 375 for 30-35 minutes until the cheese is starting to brown. You may substitute lasagna noodles for the rotini, but this will take longer to layer. I don't usually use all the sauce or cottage cheese if I am making a single batch. That is personal preference.
