Begin by melting the butter in a medium stockpot over moderate heat. Cut your veggies into small pieces, as this soup cooks fairly quickly.
Add the onion, celery, and carrot and cook, stirring occasionally, for 12-15 minutes or until well browned. You want the veggies well browned because that will lend a depth of flavor to the soup.
Once the veggies are soft and browned, add the garlic and cook for 1 minute.
Add the bone broth, water, turmeric, bay leaves, and kale. Also, add the reserved juices from the rotisserie chicken. Bring the soup to a boil and reduce to a simmer and cook for 25-30 minutes or until the carrots are very tender.
Once the veggies are tender, add the chicken, salt, and pepper to the soup. Allow the chicken to heat through.
Meanwhile, bring a small stockpot of salted water to boil. Add the keto palm noodlesa and cook for 3 minutes until al dente, or as per your package directions. Drain and add to the soup.
Off the heat, add the juice of 1 lemon. Stir and remove the bay leaves. Serve immediately!
