Whole-Wheat Pasta with Lentils, Spinach, and Leeks
French green lentils, sometimes called lentilles du Puy, hold their shape well once cooked, making them particularly suited to salads and pasta dishes. Like other legumes, lentils are low in fat and are exceptional sources of folate, iron, and protein, plus other vitamins and minerals. Here, the lentils are combined with whole-wheat pasta shapes called chiocciole (snails), but you can substitute penne or any other short tubular shapes. If you like, grate or shave parmesan over the pasta just before serving.
