This delicious soup is the perfect meal when you want something warm and comforting that doesn’t feel too heavy. As an added bonus, it calls for leftover or pre-cooked chicken for a shorter cooking time that gets this recipe done in under 30 minutes.   Lemons are a great source of vitamin C, which is best known for its immune benefits but also plays a major role in collagen synthesis, hormone production, and iron absorption.  I also love the ease of adding cauliflower rice to this soup, which you can find frozen in most supermarkets these days. You can also just finely chop a head of cauliflower yourself. It’s high in vitamins C, K, and B6 and it also contains several antioxidants, including indole-3-carbinol which may reduce the risk of certain kinds of cancers. When we use a variety of real ingredients like this, food truly is medicine.  Wishing you health and happiness, Mark Hyman, MD
