Use a large roast-pan or bowl which you would cook casseroles in the oven, and put a thin layer of macaroni upon the bottom, and then spread cheese over that layer, and repeat this layering process until the cheese and macaroni are gone (makes about 3-4 layers each).
Mix salt, pepper, eggs and milk together.
Pour into layered macaroni & cheese, until filled at the top (or until it is gone).
Sprinkle w/ paprika on top.
Place in oven, Bake at 350 degrees for about 45 minutes (covered).
