This easy soup is full of immunity-boosting foods: vitamin C-rich kale, vitamin D-enhanced mushrooms, zinc-containing chicken and chickpeas, and antioxidant-packed garlic. Plus, the hot, steamy broth and a hint of pepper heat get your nose running—great for flushing out sinuses and potentially staving off an infection. It’s a big pot of brothy soup that you can make ahead and enjoy for a couple of days; the flavor just gets better over time. You may be wary of the large amount of garlic, but keep in mind that it mellows considerably after being cooked. Though we love using bone-in chicken breasts here, you can also swap in 3 cups shredded rotisserie chicken breast in a pinch (be aware that it will add more sodium).View Recipe: Immunity SoupThe 6 Immunity Boosters that Make This Soup Effective and FlavorfulChickpeas: A good source of zinc.
