Souping is a satisfying and delicious way to manage weight with tons of nutrients nourishing your body. Soups blended to a smooth purée are simple to make. Use legumes to give it body, texture and taste. If you thicken a soup with potato, blend it as soon as the potato is done or it will become overcooked and glutinous. The size of the potato pieces and the timing of their addition to the stock are important.
