Wash and cut the potatoes into bite-sized pieces. Pour the oil into a 13x9 casserole dish, and then put the potatoes in.
Chop the onions into small pieces and mix in. Cut the bacon into small pieces and mix in. Sprinkle the seasonings on top (to your taste).
Slice three quarters of the cheese and layer on top, covering the whole pan. You can use more or less cheese according to your preference.
Bake in the oven at 375°F for about 1 1/2 hours. (If you use the sausage, remove from the casings and put small chunks throughout the mixture)
