For the best flavor, buy sweet potatoes that are dark orange in color. Because they don't store well, keep them in a cool, dry, dark place for up to one week. They shouldn’t be refrigerated.
For easy preparation, make these sweet potatoes in a disposable foil pan. Just cover with foil, then grill according to the recipe.
Sweet potatoes are an excellent source of beta-carotene, an antioxidant thought to reduce cancer risk.
