Place chicken in crock-pot, add WannaRub. Mix together remaining 4 ingredients and pour over chicken. Cook 3 hours on high. Remove chicken and shred with 2 forks. Return chicken to cooker to absorb juices, adding more BBQ if needed.
Serve chicken on your favorite roll, topped with cheese or coleslaw. Or serve in a taco shell or wrap and top with lettuce, red onion, avocado, tomatoes, shredded Mexican cheese and WannaRub Garlic Aioli.
