Instructions

1. Slice the beef into thin steaks about 1/4 inch thick or less. You can do this yourself or have your butcher cut it for you.

2. Wash the meat with cold water and put it into a deep pot. Mix in vinegar and let set for at least one hour. For best results, let the meat sit in vinegar overnight.

3. Put the pot on stove and stir in salt, garlic, pepper and tomato sauce. Cook for 30 minutes on high.

4. Lower the temperature to medium. Cut the onion into rings, put them into the pot and stir them around. Add water to the pot so the meat doesn't burn and so that you will have a bit of gravy mixture. Serve over mashed potatoes.
