Crockpot Bacon Cheese Potatoes

Ingredients
¼ pound bacon, diced – I bake it first in the oven so that it is “done” and browned then I dice it and place in the crock pot.
1 small onion, thinly sliced
6 – 8 red potatoes, quartered (thinly sliced if using regular potatoes or if you use a new potato then halve)
½ pound cheddar cheese, thinly sliced (shredded is fine)
salt and pepper
butter
Green Onions (optional)
Instructions
Line crockpot with foil, leaving enough to cover the potatoes when finished – this will help to not stick and to steam the potatoes.
Layer half each of the bacon, onions, potatoes and cheese in crockpot. Season to taste with salt and pepper and dot with (real) butter.
Repeat layers of bacon, onions, potatoes and cheese. Dot with butter.
Cover with remaining foil.
Cover and cook on low for 4-6 hours.
