Becky's Beef Stroganoff

1 lb. beef (I like the petite sirloin steak cut up into 1 1/2 inch strips)
1 onion, sliced
1 clove garlic, chopped
1 recipe of Cream of Mushroom Soup or 2 cans of condensed soup
3 Tbsp ketchup
3 Tbsp Worcestershire sauce (make sure it's gluten free, Great Value currently is)
1 cup fresh mushrooms, sliced
2 cups light sour cream
salt and pepper to taste

Brown meat in pan (deep enough to add the rest of the ingredients to) add onions and garlic and cook until just soft, add cream of mushroom soup, ketcup, worcestershire sauce and fresh mushrooms, cook for 15-20 minutes, stirring occasionally, add sour cream then serve over cooked rice or noodles. Makes about nine cups.
