Combine all ingredients in your crock pot. Stir lightly to combine seasoning with the liquid. Put the lid on the crock pot, turn on low and cook for 5 or 6 hours until meat is fork-tender and falling apart. If meat is not yet tender, cook for 30 minute intervals till it's tender. Remove beef from the crock pot. With two forks, completely shred all meat, leaving no large chunks behind. Serve immediately, or keep warm in the crock pot.
