Quick Cube Steaks

Directions

1. 1
   Chop onion.
2. 2
   Melt butter in a heavy skillet over medium heat.
3. 3
   Add the steaks and onions, browning steaks on both sides.
4. 4
   While steaks are browning, mix gravy mix according to to package directions.
5. 5
   Add vinegar and brown sugar to gravy.
6. 6
   Pour gravy over steaks and lower heat. Cover and simmer 20 to 30 minutes until meat is tender. Check periodically to make sure liquid does not evaporate. Add water as necessary as the gravy cooks down and get very thick. I have simmered for up to an hour with good results. Just keep an eye on the gravy--don't want it all to evaporate.
