Follow these simple steps to create a delicious Chicken Bean Chili:

1. Prepare the Chicken: Cut the chicken breasts into small, bite-sized pieces.
2. Sauté the Vegetables: In a large pot, heat the olive oil over medium heat. Add the chopped onion and garlic, and sauté until the onion is translucent, about 3-4 minutes.
3. Add the Chicken: Add the chicken pieces to the pot and cook until they are no longer pink, about 5-6 minutes.
4. Incorporate the Beans and Tomatoes: Stir in the black beans and diced tomatoes with green chilies. Mix well to combine all ingredients.
5. Seasoning: Add the chili powder and mix until everything is well-coated. Season with salt and pepper to taste.
6. Simmer: Reduce the heat to low, cover the pot, and let the chili simmer for about 15 minutes. Stir occasionally to prevent sticking.
7. Taste and Adjust: After 15 minutes, taste the chili. Adjust spices or seasoning if necessary.
8. Serve or Store: Once fully cooked, you may serve it hot or let it cool and store in an airtight container.

Following these steps will ensure you create a delightful Chicken Bean Chili that your family and friends will love!
