Preheat oven to 425° Fahrenheit and line a large baking sheet with parchment paper. Set aside.
Cut the broccoli into large-ish florets. Place florets in a large bowl and add the avocado oil, salt, and pepper. Toss to coat evenly.
Arrange the broccoli in a single layer on the prepared baking sheet. Place in the preheated oven and roast for 15 minutes. Stir the broccoli, flipping over as many florets as possible, and roast an additional 10 minutes.
While the broccoli is roasting, cut one lemon in half and the other into wedges. Set aside.
Remove from the oven and scatter the pine and parmesan cheese over the broccoli. Then return the pan to the oven for 5 minutes.
Remove from the oven, squeeze the two halves of lemon over the top of the roasted broccoli, and give it a stir. Transfer it to a serving dish and serve with reserved lemon wedges on the side.
Store leftover broccoli in an airtight container in the fridge for up to 3 days.
