7 lb boneless sirloin tip roast
1 envelope onion soup mix
4 cups water
5 large onion, chopped
2 cans cream of mushroom soup

Cover the roast with soup mix, add water, and bake at 350F until done to your liking approximately 2 1/2 to 3 hours. Let stand about 20 minutes when done. Save the drippings to make a gravy. Sauté the chopped onions in the drippings until transparent, mix with the soup. Heat through. Serve over roast.
