Roasted cauliflower? Been there, done that. But roasting a whole head of cauliflower? Now we’ve got your attention. This recipe has you slathering cauliflower in a spicy yogurt marinade and roasting it at a high temperature. The result is an amazingly delicious dish that’s as dramatic in presentation as it is easy in preparation. It’s an easy weeknight supper or your next “the vegetarians are coming to dinner” party.
