This one is a family favorite and a weekly occurance on our family menu.
Start with onions in a large skillet. Sauté with wine and brown sugar until onions are soft and sugar is carmelized. Peel, chop, and boil potatoes until soft. Once onions are done cook cube steak in same pan (do not clean). 4 minutes each side on the cube steak (varies depending on thickness). Drain potatoes, mash, and stir in bacon and butter. Make gravy as directed and serve!
