Healthy Tomato soup: I added spicy Hungarian paprika to basic tomato soup and finished it with nonfat Greek yogurt (rather than cream) for a protein-packed yet creamy consistency.
Kale, White bean, Sausage soup: iron-rich kale and lean chicken or turkey sausage create great flavor for this winter soup.
Ribollita: Following the traditional Tuscan recipe in the Italian cookbook La Cucina Fiorentina, this hearty vegetable soup uses both collard greens and kale or chard, and both whole and blended white beans for varying textures. Ribollita means "reboiled" in Italian, so this soup should be made the night before serving, then bring to a boil again the next day, hence boiling twice, for a thick, rustic result.
Lentil soup: stewed lentils with sweet potato, carrots and spinach for a fiber-filled winter meal. When it's bitter cold below freezing, spiced lentil stew does the trick.
