Preheat oven to 425° F.
Arrange broccoli rabe in a single layer on two baking sheets.
Drizzle each sheet with half the olive oil and sprinkle with half the zest and garlic each.
Massage that into the broccoli rabe really well, making sure it's coated fairly evenly. Spread the stems back out evenly over the sheet, giving as much room as possible.
Grate parmigiano reggiano over the vegetables. Be generous. We're not using salt.
Roast for 10 minutes. Top with toasted pine nuts and serve.
