At some point in recent history, kale went from ugly duckling to prom queen and is now so trendy it may be officially headed for a backlash. But we hope not. This superfood is a nutrition powerhouse rich with vitamins A and C and many of the antioxidants that health experts implore us to consume. Although most-often lumped into the bitter green family, it is a little smoky but actually not that bitter, and it gets sweeter during the winter months. Look for crisp, tender and bright leaves; use in salads, quickly sautéed until just softened, cooked slowly with garlic and vegetable broth, use it in place of spinach in creamed spinach, or roast it for kale chips.
