In a large saucepan, bring the broth, water, carrots, onion and celery to a boil. Reduce heat; cover and simmer for 4-6 minutes or until vegetables are crisp-tender. Add the noodles. Simmer, uncovered for 20 minutes or until noodles are tender.

Stir in turkey and peas. Combine gravy mix and cold water until smooth; stir into soup. Bring to a boil; cook and stir for 2 minutes or until thickened.

Ready to serve!
