1/4 pound Bacon, diced
2 medium Onions, thinly sliced
4 medium Potatoes, thinly sliced
1/2 pound Cheddar cheese, thinly slice
Salt and pepper

Line crockpot with aluminum foil, leaving enough to overlap potatoes when finished. Layer half each of the bacon, onions, potatoes and cheese in crockpot. Season to taste and dot with butter. Repeat layers of bacon, onions, potatoes and cheese. Dot with butter. Overlap with remaining foil. Cover and cook on low setting for 10 to 12 hours.
