Introduce the chicken broth, beans, green chiles, chicken, corn, chili powder, cumin, oregano, salt, and black pepper. Let it come to a boil, then lower the heat to low. Put on a lid and let it simmer for 10 minutes until the chicken is fully cooked.
Place the sour cream in a small bowl. Ladle approximately 1/2 cup of the hot chili into the sour cream and stir until thoroughly blended. After that, transfer this mixture back into the chili and stir until all ingredients are incorporated. This technique helps keep the sour cream from separating. Serve and enjoy!
