Start by washing and slicing your bell peppers and onion into thin strips, ensuring they are uniform for even cooking. Cut the boneless chicken breasts into bite-sized pieces. Gather your fajita seasoning, chicken broth, and lime juice, ensuring everything is on hand for an easy cooking process.

Place the chopped chicken at the bottom of your crockpot, layering the sliced bell peppers and onions on top. Pour in the chicken broth and sprinkle the fajita seasoning evenly over the ingredients.

Squeeze freshly squeezed lime juice over the layered ingredients, ensuring it evenly distributes over the meat and vegetables.

Cover your crockpot and set it to cook on low for 6-8 hours or on high for 3-4 hours.

Once cooked, use two forks to shred the tender chicken right in the crockpot, ensuring it soaks up the juices.

Warm your tortillas and prepare your toppings. Serve the flavorful chicken and pepper mixture inside the tortillas.
