Turnip greens are tender leafy greens harvested from turnip plants. They have a slightly bitter, earthy flavor and are often braised, sautéed, or added to soups and stews. Commonly seasoned with garlic, vinegar, or smoked meats, they make a nutritious side rich in vitamins A, C, and K. Store refrigerated and use within a few days. Rinse thoroughly before cooking to remove grit.
