3 pounds beef roast (i used chuck roast or you could use bottom round)
2 cups water
In a food processor or blender, combine the 3 chipotle peppers (removed from the can with some adobo sauce), cilantro, onion, garlic, cumin, oregano, salt, the juice of one lime, and the apple cider vinegar. Blend until almost smooth.
Place beef in slow cooker.
Pour the homemade sauce on top. Add two cups of water.
