Soup: In an 8-quart stock pot over medium heat, melt margarine. Add onion and sweet potatoes. Cook, stirring until onions are transparent, about 10 minutes. Raise heat to high, add stock and bring to a boil. Reduce heat, cover and simmer until sweet potatoes mash easily, about 20 minutes. Mash potatoes coarsely with a fork. Add corn and turkey. Season to taste with salt and pepper. Cook through until turkey is heated. Garnish individual servings with chives or scallions.
