Place the chicken strips at the bottom of the slow cooker.
Add the sliced onion and bell peppers over the chicken.
Sprinkle the fajita seasoning over the chicken and vegetables, then drizzle the olive oil on top.
Pour the chicken broth into the slow cooker, followed by lime juice.
Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours.
Once cooked, shred the chicken with two forks and mix the ingredients together.
Serve the fajitas with tortillas, rice, or your favorite toppings like guacamole and sour cream.
