Use a peeler to make thin slices of the zucchini. When you get to the seeds, flip over and peel from other side because the seeds don't like to cooperate!
Brown the ground beef and add sauce.
Mix egg, cottage cheese and parmesan cheese in a medium bowl.
Put down a thin layer of the sauce and meat in the bottom of a 9x9" pan. Make a thin layer of zucchini on top, then a layer of the cheese and egg mixture, followed by a layer of zucchini. Repeat layering until the pan is almost full and the top layer is the sauce and meat mixture.
Spread shredded mozzarella cheese on top.
Bake on 350 °F (175 °C) for 45 minutes.
Let sit for 30 minutes before serving.
