The recipe -
Boil 1/2 pound elbow macaroni
Grease Pyrex loaf pan.
Alternate layers of macaroni and American cheese starting with the macaroni.
Break 2 eggs and pour over macaroni. Fill baking dish with milk to almost cover macaroni.
Top with bread crumbs, and parsley. Bake 350 degrees until set, usually about 45 minutes to 1 hour.
It is pretty forgiving. Just boil macaroni and add cheese. I have used whatever cheese I have in the house. Mom used American. It is a good basic recipe you can build to fit your taste.
