1 large onion, finely chopped (use a food processor if you can)
4 T. margarine
1 T. dried dill (to taste)
3 T. sour cream
1/3 c. red wine
1 T. sugar
salt and pepper to taste
Melt margarine in a skillet over medium, add onions, and cook until golden. Drain off some of the liquid rendered by the onions, then add the rest of the ingredients and simmer. I put the cooked cubed steaks in with the gravy to coat them and allow the meat to absorb some of the flavors of the gravy, but it could just as easily be spooned over the top.
