Put frozen chicken (fresh is fine too, just lower the time) in the crock-pot and cover with salsa and taco seasoning. Make sure the chicken is coated pretty well. Cook on low for 8 hours or on high for 3-4 hours.
When chicken in cooked shred with two forks and turn crockpot to warm until ready to eat. Serve with desired taco fixings and enjoy!
If you have leftover chicken it goes great on salads, nachos, in burritos or really any Mexican dish!
