This one-pot chicken and cabbage soup is topped with flavor-boosting store-bought pesto. Big, fiber-rich butter beans add a creamy bite, but you can easily swap them out for cannellini beans or navy beans if you prefer. This soup works well with leftover chicken—simply shred or chop cooked chicken and add it to the soup to reheat once the cabbage is tender.
