Slow Cooker Bajio Chicken

5 chicken breasts
1/2 cup salsa
1 Tbsp cumin
1/2 cup brown sugar (more to taste)
1 4 oz. can diced green chilies
6 oz. Sprite (1/2 can)

Combine all ingredients in a crock pot. Cook on low for 5-6 hours. Remove chicken and shred. Return to crock pot and cook 1 more hour. Thicken the juices with a little cornstarch mixed in water.
Serve with flour tortillas, lettuce, cheese, black beans and any other taco fixings.
If you want it spicier rather than sweeter add a hotter salsa and more green chilies.
