Preheat the oven 425 degrees F. Line a baking sheet with foil and spray with nonstick spray.
Place the broccoli on the sheet and drizzle with the olive oil. Cover with the pine nuts, salt, pepper and parmesan.
Roast for 20 to 25 minutes, or until the broccoli is golden brown and the pine nuts are toasted. After this time, the pine nuts may start to burn, so keep an eye on it! Remove from the oven and sprinkle with more parmesan if desired. Serve immediately.
