Creamy soups, mashed potatoes and smooth sauces are all delicious, but they are usually packed with unhealthy fats. Cauliflower is a super vegetable that is low in fat and calories, but high in nutrients and fiber. Add the lightly boiled or steamed cauliflower to your sauce or a soup, and blend it. You will get a thick and creamy texture in no time! Mashed cauliflower is also a perfect substitute for mashed potatoes. It’s lower in calories, easier to digest and tastes almost similar.
