Dice the chicken breast into small, bite-sized pieces.
Heat the olive oil in a large pot over medium-high heat.
Add the ground turkey and diced chicken breast to the pot, browning the meat until cooked through.
Add the chopped yellow onion, green bell pepper, and minced garlic to the pot, sautéing until the vegetables are softened.
Stir in the diced tomatoes, kidney beans, chili powder, cumin, sea salt, and black pepper.
Pour in the chicken bone broth and stir well to combine all ingredients.
Bring the mixture to a gentle boil, then reduce the heat to low.
Cover and simmer for 15-20 minutes to allow the flavors to meld and the chili to thicken.
Serve warm in a bowl, optionally garnished with fresh herbs.
