Heat a large, deep skillet or soup pot over medium high heat with oil. Once the oil is hot, add the carrots, celery, onion, garlic and salt. Sauté until tender.
Add chicken broth, Cumin & Garlic Taco Seasoning, chicken breast(s), tomatoes, green chilies, black beans, and 1 cup of tortilla chips. Bring soup to a low boil and cook until the chicken is no longer pink and the soup has thickened.
Remove the chicken, dice into bite size pieces, and return to soup.
Stir in milk and cheese.
Spoon soup into individual serving bowls. Top with cheese, tortilla chips, sliced avocado, and fresh cilantro. Serve with a lime wedge. Enjoy!
