I came across this recipe in The Best of Fine Cooking: 101 Quick & Delicious Recipes. I love the fact that it is such a simple and easy dish to make, and it tastes great! I usually serve it alongside grilled fish and some form of grains such as couscous.
1 small head cauliflower, trimmed and cut into florets
2 Tbs. olive oil
Kosher salt and freshly ground pepper to taste
Position a rack in the lower third of the oven and heat the oven to 400˚F. On a large baking sheet, toss the cauliflower with the oil, salt, and pepper. Spread to a single layer without crowding and roast, turning every 10 minutes, until golden brown and crisp-tender, 25 to 35 minutes. Serve hot or at room temperature.
