Preheat oven to 350°F and lightly coat the bottom of a 9x13 pan with sauce.
Cover the bottom of the pan with four or five uncooked lasagna noodles--three or four vertically and one horizontally. You will need to break the horizontal one to fit properly.
Put another layer of sauce over the pasta and add dollops of cottage cheese. Cover with zucchini slices and sprinkle with shredded carrots, chopped mushrooms, and chopped greens.
Add another layer of noodles and repeat the previous step. Keep adding layers until you run out of noodles and filling (three layers total).
Generously sprinkle the top with shredded mozzarella. (Don't worry if it's enormously tall and piled up over the sides of the dish--it will reduce as it bakes!)
Cover with aluminum foil and bake for 30 minutes. Then remove the foil and bake for about another 30 minutes or until the top is golden brown. You could also broil it for the last few minutes to help with the browning.
Let cool for a few minutes before serving. Enjoy!
