Curried Carrot, Sweet Potato, and Ginger Soup

This soup gets its wonderfully creamy texture from purèed carrots and sweet potatoes rather than cream, a dairy product Willett discourages due to its high saturated-fat content.Don't worry about saturated fat or cholesterol with this creamy soup. Carrots and sweet potatoes are rich in vitamin A and beta-carotene, which promotes healthy vision. Add whole grain crackers for fiber and dipping.
