Preheat oven to 375° F
Drain the cottage cheese and mix with mozzarella, leaving 1/4 - 1/2 cup of mozzarella to sprinkle on top of lasagna.
Spread 1 Tablespoon of sauce on bottom of 9x13 casserole dish to prevent sticking of noodles. See sauce recipe here: http://www.allthecooks.com/recipe/Perfect+Spaghetti+Sauce-58736210/

Repeat steps 3-5 with remaining noodles, sauce and cheese.
Sprinkle reserved mozzarella cheese over top of completed lasagna.
