Mostly Cauliflower-Leek Soup- a recipie redux

When it is a rainy, chilly night, there is nothing more comforting then a warm bowl of soup.  I love potato-leek soup, but wanted to make a healthier, lower carb version. I took my regular potato-leek soup recipe and cut the potatoes down to two small yukon golds.  I replaced the rest of the potatoes with a head of cauliflower.  I omitted the cauliflower part from my husband when describing what I was making for dinner. I didn't tell him until after he'd eaten the soup that it was in fact, made mostly with cauliflower. He said he didn't know the difference.  It is still satisfying, creamy and delicious. Trust me, you don't miss the potatoes at all.
