Slideshow: Roasted Vegetables
Preheat the oven to 400°. On a large baking sheet, toss the broccoli florets and stems with 2 tablespoons of the olive oil and season with salt and pepper. Roast the broccoli in the oven for about 30 minutes, tossing halfway through, until browned and tender.
Meanwhile, in a small skillet, toast the pine nuts over moderate heat until light golden all over, about 4 minutes.
In a small bowl, whisk the lemon juice with the shallot and the remaining 2 tablespoons of olive oil; season the dressing with salt and pepper. Scrape the broccoli into a serving bowl. Add the dressing and toasted pine nuts, toss well and serve.
