Preheat your oven to 375 degrees f. and line a large baking tray with parchment paper.
Place your prepared sprouts on the baking tray, drizzle with oil, and season with sea salt and pepper. Give everything a good toss before carefully arranging them in a single layer.
Roast for 25-30 minutes, or until tender center with a browned-crisp outside.
Meanwhile, very thinly slice your apples and drizzle them with some fresh lemon juice to prevent apple slices from browning.
Once your sprouts are ready stir in the apples, pecans/walnuts, maple syrup/raw honey, and the shaved parmesan. Toss everything to combine well, then arrange in single layer again.
Reduce the heat of your oven to 350 degrees f.
Return your tray to the oven and continue to bake for 5 more minutes.
Serve warm.
Enjoy!
