Turnips are a root vegetable with many uses. It is a good source of vitamin C (especially the greens), vitamin A, folic acid and calcium. The greens can be used in salads or cooked like spinach. I have found that the greens are easily overcooked so I would advice sautéing some garlic and/or onions in oil, and adding the greens to cook briefly at the end.  Do not delay in eating them as they will continue to cook/steam in the dish!  Some like the roots raw.  They taste much like a radish.  Cooked roots compliment potatoes, are tasty on their own or used in other preparations.  This recipe is a favorite for our family.  We love the sweet flavor of these steamed turnips.
