Who ever said that soup has to be warm? Who ever said that soup is only for the winter time? Well… they were wrong. This chilled watercress spinach soup is perfect for a hot day, especially in the south, where it is common to hit 90 or above in July (or occasionally June). You can use hard-boiled egg for the garnish, but you can also do freshly chopped herbs to give the dish a little something extra. Basil, cilantro, or parsley would be great choices!
