1 pound boneless skinless chicken breasts, chopped
1 medium onion, chopped
1 tablespoon olive oil
2 garlic cloves, minced
2 cans (14 ounces each) chicken broth

In a Dutch oven over medium heat, cook chicken and onion in oil until lightly browned. Add garlic; cook 1 minute longer. Stir in the broth, chiles, cumin, oregano and cayenne; bring to a boil.
Reduce heat to low. With a potato masher, mash one can of beans until smooth. Add to saucepan. Add remaining beans to saucepan. Simmer for 20-30 minutes or until chicken is no longer pink and onion is tender.
