Add chicken to slow cooker. Sprinkle taco seasoning over both sides of chicken.
Add remaining six ingredients to the slow cooker.
Cover, cook on low for 6-8 hours. If you notice the liquid is too thin for your liking, add 3 teaspoons of cold water, 3 teaspoons of corn starch to a glass and mix until no lumps remain. Add mixture to slow cooker before time is up and let cook for 15 -30 minutes.
Once the chicken is cooked through, break into pieces and add in the white beans, corn and cilantro. Mix well and let sit until corn is warmed.
