Put meat in crock pot and set on high. Pour soups over top of meat. Cover and cook for 6-8 hours on low, until tender.
3 pounds beef roast, 1 can cream of mushroom soup (10 3/4 ounces), 1 can cream of chicken soup (10 3/4 ounces)
Remove roast and slice thinly. Add back into crockpot gravy.
Serve on crusty rolls, with gravy in small bowls for dipping.
Notes
If your meat is frozen, it will take longer to cook. You can set the crockpot on high in that case in order to ensure the meat is thoroughly cooked. You do not need to mix the soups together, they will blend naturally. Feel free to mix and match different 'cream of' soups, depending on what is available in your cupboard.
