I modified a recipe for Beef Stroganoff all over the web:
2 lb. beef sirloin cubes, raw
2 sm. onion, chopped
2 cloves garlic, minced
2 can cream of mushroom soup, undiluted
3 tsp. Worcestershire sauce
8 oz Package of fresh mushrooms, sliced
1/2 cup of red wine (I used Ravines Keuka Village Red which has a nice hint of peppercorn)
16 oz. sour cream
Mix all ingredients except sour cream in crock pot. Cook for 8-10 hours on low. When done, mix in sour cream well and cook on high for 15-20 minutes.
Serve over noodles or rice.
And everything turned out well.
