2 c. mashed potatoes (great for leftover mashed potatoes)
Milk
Salt & pepper
1 egg, beaten
4 tbsp. minced onion

Mix potatoes, egg, onion, salt and pepper. Add milk until mixture stirs easily and can be shaped into patties. If you get the mixture too thin, add a little flour. Fry patties in a small amount of oil until brown on both sides.
