Hearty Chicken Tortilla Soup with Beans

Bring water and 2 teaspoons salt to a boil in a large Dutch oven or heavy-bottom stockpot. Add chicken, cover Dutch oven, and cook until chicken is no longer pink in the center, 10 to 15 minutes. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C). Transfer chicken to a plate to cool and pour water from Dutch oven into a bowl for later use.

Heat olive oil in the Dutch oven over medium heat. Cook and stir onion and bell pepper in hot oil until onion is soft and translucent, 4 to 5 minutes. Add garlic to onion mixture; cook and stir until garlic is fragrant, about 1 minute.

Mix chicken broth, black beans, Great Northern beans, diced tomatoes, green chile peppers, chili powder, oregano, cumin, and salt into onion mixture. Bring to a boil, reduce heat to medium, cover Dutch oven, and simmer until soup flavors blend, about 20 minutes.

Remove bone from chicken and discard. Shred chicken meat into small pieces using your hands or a fork. Add chicken and corn to soup; cover Dutch oven and cook until corn is warmed, about 5 minutes.
