Simmer the soup another 10-minutes. Add black beans, corn, lime juice, chopped cilantro, and shredded chicken to the pot and cook for additional 5 minutes.
Taste, and add salt and pepper to taste, and any other additional spices depending on your preferred spice level. Simmer for a few more minutes to let flavors meld. Remove oregano sprigs.
