When beef is almost cooked add 1/4 cup of taco seasoning (see recipe below) and 1/2 cup of water
Turn the burner to 'low' and simmer until juices are gone
While beef is cooking finely shred the cabbage with a food processor or knife
Melt butter in a large frying pan
Add cabbage and onion to the pan and fry until soft, this may take awhile
Once cabbage is soft add white wine vinegar and heat for a few more minutes
