Place all the ingredients in the slow cooker. Give them a good mix. Cook for 6-8 hours on low or 4-5 on high. You'll know it's done when it's thick and the chicken is soft and tender.
Remove chicken from slow cooker and shred with two forks then return to slow cooker. Mix to combine.
Top with fresh avocado slices, sour-cream, tortilla chips, cilantro, or your favorite toppings. Enjoy!
