Begin by placing the 2 lbs of boneless skinless chicken breasts at the bottom of your slow cooker.
Layer the sliced bell peppers and halved yellow onion on top of the chicken.
Pour the can of petite diced tomatoes with green chilies over the chicken and vegetables. In a separate bowl, mix the minced garlic, chili powder, ground cumin, paprika, ground coriander, salt, and pepper. Sprinkle this spice blend over the top.
Drizzle the fresh lime juice and honey over the entire mixture, ensuring everything is well coated.
Cover the slow cooker and cook on low for 6-7 hours or high for 3-4 hours, until the chicken is tender and easily shreds with a fork.
Once cooked, remove the chicken breasts from the slow cooker and shred them using two forks. Return the shredded chicken to the slow cooker and stir to combine everything.
Warm the tortillas in a dry skillet or microwave. Serve the chicken fajita mixture in the tortillas and top with your favorite toppings like cilantro, sour cream, salsa, guacamole, or shredded cheese.
