I don't know the origin of this recipe, but I've been making it for years, and it was always a family favorite. You can use as much, or as little, cheese as you like and any combination of cheese that suits you. I usually put parmesan down as my first layer, top that with shredded cheddar and then top that with some shredded mozzerella. (I like cheese). I have always used 1 1/2 cups of the dried elbows, 'cause I like my dish a little thicker. Enjoy.
