Beef stroganoff

1 boneless sirloin, cut into strips (ground beef would work too, but not as good)
1/3 cup butter
2 medium size onions-sliced
1 can condensed beef broth
1 tsp salt
2 tbps flour
1 cup sour cream

Add 1 tbsp butter to skillet and pan fry steak about 1 min on each side or until cooked to your preference. Remove steak, add rest of butter, stir in onion and saute 5 min. Stir in mushrooms and saute 3 min add beef broth and salt, simmer 5 minutes. stir flour into sour cream in a small bowl, blend in about 1 cup of the hot mixture and then return the sour cream mixture to skillet and cook, stirring constantly until mixture thickens and just begins to bubble (do not boil) add steak - serve with egg noodles or rice.
