  • In another frying pan, heat 2 TBS butter. Add minced onion and mushrooms. Cook over medium heat 2 minutes. Add 2 TBS wine and cook 2 minutes more. Add mushroom mixture to meat mixture. Check seasonings and add warmed sour cream.
  • Over lowest possible heat, simmer for 5 minutes to heat through. Do NOT let it boil.
