Preheat the oven to 350 degrees F.Cook the noodles according to the directions on the package. Drain, set aside and keep warm.
Saute the garlic and onion in the olive oil, adding a little water as needed to keep from sticking. Add one bag of spinach and saute until completely wilted.
In a very large bowl combine the tofu, ricotta cheese, parmesan cheese, egg, oregano, garlic salt, parsley, black pepper and sauted spinach mixture. Mix well.
Spray a 9×13-inch pan with cooking spray. Arrange a layer of cooked noodles at the bottom and top with 1/3 each of the ricotta mixture, the tomato or alfredo sauce, a handful of uncooked spinach and some mozarella cheese. Repeat the layers twice more, ending with the sauce and cheese.
Cover with foil and bake for about 40-45 minutes. Remove the foil and bake for about 10-15 more minutes to brown the cheese.
