Follow the recipe for Oven-Charred Broccoli; while the broccoli is roasting, in the same bowl used to toss the broccoli with oil and seasonings, stir together 3 tablespoons extra-virgin olive oil, 3 tablespoons lemon juice, 2 ounces Parmesan cheese (shaved), ½ cup roasted pistachios (roughly chopped) and ½ cup lightly packed fresh flat-leaf parsley (chopped). As soon as the broccoli is done, scrape it into the bowl and toss to combine. Taste and season with kosher salt and black pepper, then transfer to a serving dish.
