Super Simple Roast Beef Sandwiches

Why I Love This Recipe
This is easy and great for parties! My sister in law served it for her son's graduation. The recipe doubles easily and can be frozen for later use.
Ingredients You'll Need
Beef Roast, 2-3 pounds
1 envelope dry onion soup mix
1 can cream of mushroom soup (10-11 ounces)
Directions
Place roast in crock pot and sprinkle with dry onion soup mix. Add about 1 cup water. Cook 6-8 hours on Low.
2. Remove meat from crock pot and reserve. Drain off broth. Place roast back in crock pot and break into small chunks with a fork or if necessary, a knife.
3. Return the cooked, separated meat to the crock pot and add cream of mushroom soup. Stir well. Heat until warm and serve on buns.
