Azerbaijani Kefir and Greens Soup

My new favorite book, “Olive Trees and Honey” by Gil Marks, is the source of this delicious soup. If Kefir is not available to you, substitute plain yogurt. This soup is best served freshly warm just as it is done, and is traditionally served after the main course. The long total time for preparation includes 4 hours of soaking the split peas before making the soup, which I included as “cooking” time.
