This soup is a take on the pea and mint soup I just posted but I just added cauliflower florets to the chicken broth and onions (of course removed the peas and mint). My favorite and final special touch was to add some white truffle oil to kick this up a notch. It is similar to Celeriac soup I've made before but a LOT less fattening. I used one head of cauliflower for this recipe. Cut up head and boil in chicken broth until tender then blend. Add white truffle oil after blending to taste. Mmmm...so good.
