We made this filling soup from recent (December 2010?) issue of Bon Appetit. The soup calls for French green lentils, which are small, dark green, and speckled with black. We found them at a specialty foods store. It is suggested that you begin with 2 Tb of your favorite curry powder (we used Madras) and then add more according to your taste. We liked the idea of adding pureed chickpeas to the soup, which makes it different from other lentil soups we've seen. It thickens the soup without adding the calories you might get from a flour roux or heavy cream. The recipe says it makes 6 servings, but DH and I were very hungry today at lunch and ate the entirety, so I am listing it as 4.
