Classic Beef Stroganoff

1lb beef sirloin steak or tenderloin (in a pinch, sub ground beef or ground turkey: consider getting a roast and cutting that up to be more budget friendly. I like to bake the roast before cutting up for this recipe.)
1/2lb fresh mushrooms
1/2c minced onion
2T butter or margarine
10-1/2oz beef consomme
2T catsup
1 small clove minced garlic
1t salt
3T flour
1c sour cream
3-4c hot, cooked noodles (or rice)

Cut meat diagonally in to very thin slices.
Cook and stir mushrooms and onions in butter until tender, then remove from skillet.
In same skillet, brown meat lightly.
Set aside 1/c consumme but combine rest of consumme, catsup, garlic and salt in to skillet.

Cover and simmer 15m.
Blend reserved consumme and flour, stir in to skillet.
Add mushrooms and onion, heat to boiling, boil for 1 minute.
Stir in sour cream, heat through.
Serve over hot noodles or rice.
