Place large baking sheet in the oven and preheat to 500. In a mixing bowl, toss the cauliflower with oil until evenly coated. Remove baking sheet from oven, and place cauliflower flat sides down. Bake about 12 minutes until crispy and almost tender. Remove and turn oven to broil. Put cauliflower back in the mixing bowl, and lightly toss with wing sauce. Put cauliflower back on baking sheet and broil about 2 minutes.
