After you’ve made Chef Seamus Mullen’s sumptuous Roast Chicken With Dukkah and Citrus, use the leftover meat and veggies for this wholesome and satisfying soup. This soup isn't just a good way to use up leftovers, it's also rich in nutrients, which means it'd be a great help to anyone who's sick. Sumac is used in Mediterannean and Middle Eastern cuisine and has extremely high levels of antioxidants. Kale is rich in antioxidants and electrolytes and is one of the most nutrient-dense foods in existence. Finally, ginger aids digestion and has anti-inflammatory properties.
