This swiss chard soup is vegan, but that doesn’t mean that it’s short on flavor. The key to the soup’s rich consistency is using a blend of whole and mashed beans—the mashed ones break down into the broth and thicken it, while the basil-almond pesto adds a pop of flavor on top of each bite of soup. The recipe is pretty flexible—so feel free to make do with what you have on hand. Navy beans or Great Northern beans also work in place of the cannellini, if you can’t find them at the store. Similarly, spinach can sub in for chard.
