Like other legumes, lentils are low in fat and high in protein and fiber, but they have the added advantage of cooking quickly. Lentils have a mild, often earthy flavor, and they're best if cooked with assertive flavorings. The best, most delicate lentils are the peppery French green lentils. These hold their shape well, but take longer to cook than other lentils. French green lentils = Puy lentils = lentilles du Puy = lentilles vertes du Puy These choice lentils were originally grown in the volcanic soils of Puy in France, but now they're also grown in North America and Italy. They're especially good in salads since they remain firm after cooking and have a rich flavor. They cook a bit slower than other lentils.
