Roasted Broccoli with Pine Nuts and Balsamic Vinaigrette

Simple and versatile, this side dish is essentially a warm broccoli salad dressed with a tangy vinaigrette. The flavor may be a revelation to you if you don't care for boiled or steamed broccoli-high-heat roasting brings out a delicious sweetness. If you buy broccoli tops with the stems already trimmed away, buy 1 1/2 pounds.
