This recipe is aptly named. They do not come any easier than this one. Crockpot Bachelor Roast

1 medium roast (any size, even the cheap, tough cuts)
1 can coca-cola
1 16 oz. bottle of ketchup (generic, or whatever is on sale)

Put all ingredients in crockpot and cook it for several hours until the
meat falls apart and your house smells great! The coke will break down
the tough fibers in the meat, so even the toughest comes out tender and
tasty. This recipe is good enough to serve to the best company, and
leftovers (if you have any) make good BBQ sandwiches.
