Cauliflower, Asparagus and Red Pepper Soup

New research has found that consumption of increased amounts of cruciferous vegetables is associated with improved breast cancer survival rates. Other studies have suggested that cruciferous vegetables may decrease risk of many cancers. Red peppers are high in lycopene, another cancer fighting component of vegetables. Add fresh spring asparagus and you have a healthful and tasty soup.
