Heat the olive oil in a large pot over medium heat. Add the onion and jalapeño and saute until tender, about 5 minutes. Add the garlic and saute another 30 seconds.
Add the cooked chicken, broth, beans, corn, green chilies, cumin and oregano. Stir well to combine and bring to a simmer. (See notes below if you’re using boneless, skinless chicken breasts.)
Reduce heat and let simmer for at least 10-15 minutes.
Mash 1/4 to 1/2 of the beans, if desired, then let simmer for another 5 minutes to help everything combine.
Serve hot with desired toppings and enjoy!
