Method
 

  1. If using chicken breasts, trim any excess fat. You can leave them whole in the slow cooker or slice them into 1-inch thick portions for faster cooking and easier shredding later. Slice the onion and bell peppers thinly.

  5. Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, or until the chicken is cooked through and tender.
  6. Once cooked, remove the chicken from the slow cooker and place it on a cutting board. Using two forks, shred the chicken. Alternatively, if you prefer sliced fajitas, you can slice the chicken directly in the slow cooker before serving.
