Roasted Cauliflower with (or without) Tahini Dressing

Cauliflower is one of those vegetables that you know you should eat all the time, but sometimes it's hard to make it yummy enough to want to eat often. One of my favorite cauliflower recipes is a Middle Eastern dish called "arnabit," which is basically cauliflower roasted until it's brown and crispy with a seriously garlicky tahini dressing on top.
