Shape the meat into 4 or 5 patties, handling it as little as possible. Melt half the butter in a skillet, add the onions and saute over low heat until golden. Add the pepper rings and half cup boiling water. Season with salt and pepper to taste, remove from heat and keep warm. Season the meat on both sides and saute it in the remaining butter in the skillet until it is of desired doneness. Top each patty with the onion mixture and serve with potatoes and cucumbers if desired. Makes 4 or 5 servings.
