Pour half of the canned tomatoes in bottom of crock pot. Spread in an even layer. Top with half of the peppers and half of the onion slices. Sprinkle garlic in. Top with chicken breasts.
Sprinkle the chili powder, cumin, paprika, salt and pepper over chicken breasts. Top chicken with remaining canned tomatoes, peppers and onion.
Cover and cook on LOW heat 6 to 8 hours, or on HIGH heat 3 to 4 hours, until chicken is cooked through and veggies are tender. Remove chicken and shred. Ladle out 1 or 2 cups of broth from crock pot and discard.
In a small bowl whisk together lime juice and honey. Add to crock pot along with chicken. Gently toss to combine. Serve warm in tortillas with desired toppings. Enjoy!
