Place chicken breasts in the slow cooker with 1/4 cup of the broth and cook on high for 2.5 hours (or low for 5). Ensure chicken is about 90% cooked throughout. Shred the chicken inside of the slow cooker.
Add the rest of the ingredients in the slow cooker and stir. Cook for another 2.5 hours on high or 5 hours on low (or until vegetables have softened).
Add tortilla chips, serve, and enjoy!
