Soak top and bottom of a clay pot in water for at least 15 minutes. In a mixing bowl, combine cottage cheese, four ounces cheese, egg white, oregano, basil, and parsley; set aside. In a skillet over medium heat, cook onions and mushrooms until tender. Spoon a little sauce on bottom of pot. Cover with a layer of noodles and some mushroom-onion mixture. Repeat layers until all ingredients are used, ending with noodles. Sprinkle with parmesan and remaining Monterey Jack cheese. Cover and place in a cold oven. Set temperature to 400. Bake for one hour. Remove lid to brown top for ten minutes. Allow to set for ten minutes before serving.
