In a large saucepan, heat one tablespoon of oil; cook chicken pieces until no longer pink. Remove the chicken from the pan.
Add another tablespoon of oil to the pan. Saute the carrots, celery and onion over medium-heat until crisp-tender. Return the chicken to the pan. Stir in the broth, Alfredo sauce, soup mix and basil. Bring to boiling; reduce heat. Simmer, covered, for 15 minutes. Stir in the cooked pasta, and heat through. Serve!
