In a large saucepan, add the chopped carrots, celery, onions, and garlic with some olive oil, salt and lemon pepper, and sauté until soft about 10-12 min.
Then add your broth and chicken breasts and cook for about 15-20 min or until done. Remove the chicken and shred with a fork and add back in the soup along with your riced cauliflower.
Add your fresh chopped or dried mint, lemon juice, and some more lemon pepper and salt to taste if needed. Cook for about 5 more min until cauliflower is soft and enjoy.
Adjust your seasonings accordingly and enjoy!
