Preheat oven to 350 degrees F. Spray a 1 1/2-quart baking dish with nonstick cooking spray; set aside. Cook the macaroni according to package directions. Meanwhile, place the cottage cheese in a blender or food processor fitted with the steel blade and process until it is smooth. In a large bowl, combine the processed cheese, low-fat and fat-free cheddar and cottage cheeses. When the macaroni is cooked, drain and add to the cheese mixture. In a separate medirum bowl, mix together the egg substitute, skim milk and pepper; mix with the macaroni mixture. Pour the mixture into a prepared baking dish and bake about 45 to 55 minutes or until it is golden brown on top.
