As a vitamin A powerhouse, sweet potatoes are a highly nutritious side dish. Both flavorful and rich in antioxidants, they can be prepared in a variety of healthy ways. Try these options that taste great without relying on butter and marshmallows:

• Bake, microwave, or grill sweet potatoes and top them with zero-calorie, butter-flavored spray and cinnamon
• Drizzle slices with olive oil and sprinkle with parmesan, then roast
• Peel and cube, then boil; drain and mash with low-fat sour cream, salt, a little brown sugar, and chopped walnuts
• Substitute some of the fat in baking recipes (such as breads and muffins) with mashed, cooked sweet potato.
