1 can cream of mushroom soup (or other cream sauce)
Grease a deep-dish pie plate or casserole. Place sliced potatoes evenly on the bottom, spread onions over them, and add salt and pepper to taste. Top with pork chops, then spread cream of mushroom soup (don't add water) or cream sauce over the top. Bake at 375 degrees F for about 1 hour, until the potatoes are cooked through and the pork chops are tender.
