So... A friend of mine asked for my recipe. I dont exactly have one but I can estimate for you.
1/2 small onion
1/2 T. Garlic, minced
1 small can mushrooms
1/2 C. Butter
1/2 C. Flour
1 lb steak, cut in small strips
2 C. Beef broth
1 C. Sour cream
Saute first 3 until onions are soft. Add butter and flour to make a roux (equal parts, thickener). Add steak and cook until almost done. Slowly add broth and allow to thicken. Should be a gravy consistency. Add sour cream. Serve over noodles or rice.
Salt and pepper to taste. Occasionally I add extra beef base for enhanced flavor.
