French Lentil Soup With Sweet Potato Croutons Recipe

A simple and delicious recipe for those who want to make a warm and easy meal, with some seasonal fall ingredients, on a cold night. Lentilles du Puy, which come from the Haute-Loire region of France, are pretty unique in both flavor and consistency: unlike other lentils, they'll stay quite firm even after an extensive period of cooking.  Best eaten with sliced French or sourdough bread.
