This has got to be one of the most delicious and easy soups I have made all year. I totally stumbled into this cauliflower soup the other day, when I came home from the farm with a few too many heads of gorgeous purple cauliflower. My instinct is usually to roast, so I almost went to throw it in the oven as I usually do, but I decided to try something different and wow, am I glad that I did!
