Chopped Steaks

This is a recipe I use occasionally that my family enjoys.  The gravy is rich and yummy.

1 lb. ground beef (I like to use the 80% lean)
1 lb. pork sausage
1 tsp. onion powder
4 tbsp. butter
dash Worcestershire sauce
1 tsp. dry mustard
2 tsp. salt
ground pepper to taste
2 eggs, lightly beaten
2 tbsp. sour cream
1 small can sliced mushrooms
flour to thicken

Thoroughly mix the meats with onion powder, Worcestershire, mustard, salt pepper and eggs.  Melt butter in heavy skillet.  Form meat into patties and fry.  Remove patties and cover with foil to keep warm.  Add the sour cream and mushrooms to the drippings and simmer, stirring to combine.  Use flour to thicken if needed.  Return the patties to the skillet to keep warm on very low heat until serving.
