White Sweet Potato & Cauliflower Soup

Potato Cauli Soup
By: Claire Georgiou, Reboot Naturopath, B.HSc ND

Sweet potatoes and cauliflower are an ideal combination for a soup because adding a small amount of a starchy vegetable to a low-starch vegetable meal will give it a thicker consistency. This will give you the taste and texture of a more filling soup with less calories. Cauliflower soup and cauliflower mash are my go to for a comfort meal, and by adding a little starch it gives it a more enjoyable texture and taste.  White sweet potato has a milder, sweeter taste than the regular orange sweet potato and is a nice way to switch things up to add more variety to your diet.
