In your slow cooker, stir together the broth with the chili powder, cumin, salt, paprika, onion powder, and garlic.
Add the cans of drained, rinsed beans, the drained can of corn, the diced green chilies, the tomato sauce, and the diced tomatoes.
Add the chicken. Stir the soup to combine all of the ingredients.
Cook the soup in your slow cooker on low for two to four hours or on high for six to eight hours.
Serve the soup plain, topped with sour cream, or sprinkled with cheddar cheese.
If you like, add a handful of corn chips to the top of the soup to add interesting texture and crunch. This soup is also very taste topped with a sprinkle of shredded cheese.
Store leftovers in a tightly covered container in the refrigerator for up to three days.
To reheat the soup, microwave it in a microwave-safe dish for about a minute and a half.
Alternately, you can reheat the soup by putting it in a saucepan and bringing it to a simmer over medium heat.
