1. Prep your onion, celery, and carrots. 2. Add all the soup ingredients except for the salt & pepper, cilantro, and lime juice to your Crockpot. I like to give everything a good stir prior to adding the chicken breasts. Cook on low for 6-8 hours. 3. Once the soup is cooked, shred the chicken with 2 forks and stir in the cilantro and lime juice. Season to taste with salt and pepper if desired. 4. Garnish the soup with any/all of the garnish suggestions. Serve immediately.
