a McCasserole. go to mcdonalds and get a bunch of chicken nuggets, then go to the grocery store and get a variety of shredded cheeses. take a glass baking pan, put a layer of nuggets on the bottom, then cheese, then nuggs, then cheese, and if you have the room, another layer of nuggs and cheese. bake at like 350 until the cheese on top browns.
is this disgusting? yes. was it cheap? very yes.
