Scalloped potatoes are a favorite American dish although there are many variations, usually family favorites, such as adding cheese, ham, or even sausages.
Other variations include chives as well as onions, mushrooms, or bits of bacon or other meat.
The basic recipe consists of just sliced potatoes, a generous amount of sliced onions, butter and seasonings, plus either a white sauce or milk.
These are often layered in a casserole or ovenproof baking dish, then baked at a medium or slow heat until a golden brown.
The following, which is also very simple to put together, adds tomatoes, as well as cheese. Tomato-Potato Casserole 2 large potatoes, boiled and peeled 2 large onions, sliced thin 3 large tomatoes, in thick slices 4 tablespoons butter 3/4 cup grated Parmesan cheese Salt and pepper to taste 1/4 cup water
