  1. Add half of the sliced peppers and onions to the slow cooker. Place the chicken on top and sprinkle on both sides with the taco seasoning. Add the garlic, juice of half the lime, and canned tomatoes, then the remaining peppers and onion and juice from the remaining lime half.
  2. Cook on high for 3-4 hours.
  3. Remove chicken and cut/shred into slices (chicken cooked longer will tend to shred more, cook to your preference).
  4. Return the sliced chicken to the slow cooker to marinate in the juices for about 10 more minutes on low until ready to serve. Drain any excess liquid, if desired.
  5. Add the fajita chicken to flour tortillas and top with shredded cheese, sour cream, and guacamole.
  6. Enjoy!
