Add all ingredients to the crockpot. Add 4-6 boneless chicken breast halves (completely defrosted) to the slow cooker and coat with the salsa mixture. Cover and cook on Low for 6 hours. Serve the chicken with the salsa mixture spooned over the top. If you're feeling crazy, throw a dollup of sour cream on top with some crushed tortilla chips.

This is also delicious as a taco filling or in a taco salad.
