Cook the Chicken:
Stovetop: Place chicken breasts in a saucepan with water. Bring to a boil, then reduce heat and simmer for about 10 minutes, or until the internal temperature reaches 165°F (74°C).
Air Fryer: Cook at 350°F (175°C) for 12–15 minutes, depending on thickness, until the internal temperature reaches 165°F (74°C).
Shred the Chicken:
Once cooked, allow the chicken to cool slightly, then shred using two forks. Set aside.
Prepare the Chili Base:
In a large pot, combine minced garlic, diced celery, and diced red onion. Sauté over medium heat until vegetables are softened.
Add the undrained white beans, drained corn, chopped kale, diced green chiles, chicken broth, ground cumin, and salt. Stir to combine.
Simmer the Chili:
Bring the mixture to a boil, then reduce heat and let it simmer for about 15 minutes, allowing the flavors to meld.
Add Chicken and Yogurt:
Stir in the shredded chicken and fat-free Greek yogurt. Continue to simmer for an additional 5 minutes, ensuring the chili is heated through.
Serve:
Ladle the chili into bowls and garnish with fresh cilantro or diced green onions, if desired.
