Set slow Cooker to Low - 4 Hours
Start by setting your slow cooker to low and place your slow cooker liner in.
Empty your chicken broth, cream of chicken soup and taco seasoning into the cooker. Whisk until all ingredients are incorporated.
Now add your can of diced tomato & green chilies, juice and all.
Drain and rinse both black & pinto beans in a strainer, then add to your slow cooker. At this time drain your sweet corn and add it in, this is optional. Stir.
Now place your chicken breasts in the cooker and close lid for 3 hours.
At 3 hours take your chicken breast out and place on cutting board. With 2 forks shred your chicken breasts and add the shredded chicken back into the slow cooker for an additional 30-60 minutes.
At 4 hours set to warm and serve later or turn off the cooker and let soup cool down a bit before serving.
