Feeds an army, and great for winter weather. Big hit at last night's gathering, and there isn't a shred left..

3lb beef roast
1/2 c vegetable oil
1/3 c katsup
1/4 c red wine
1/4 c minced onion
1 1/2 t salt
1 T Worchestershire sauce
1 t oregano
1/2 t dried mustard
1/4 t cayenne pepper
1/4 t pepper
1/2 c water
1 bottle spicy barbeque sauce

Place roast in large crock pot. Mix together all other ingredients EXCEPT b.b.q. sauce, and pour over roast. Simmer about 5 hours, until roast falls apart. Take roast out of crock, throw out the marinade. Shred the beef and return it to the crock, add b.b.q sauce. Cook again over low heat until heated through, stirring often. Serve as sandwich meat, or over rice.
