1. Preheat your oven to 375°F (200°C). Prepare a large baking sheet by lining it with parchment paper or lightly greasing it with non-stick spray. 

2. In a large bowl, toss the Brussels sprouts with the olive oil, and season them with the seasoned salt, garlic powder, and black pepper. Stir until everything is coated evenly.

3. Spread the Brussels sprouts on the prepared baking sheet, cut side down, in a single layer. Roast them in the preheated oven for 20-25 minutes, or until they are tender and slightly caramelized.

4. While the Brussels sprouts are roasting, prepare the balsamic glaze. In a small saucepan over medium heat, combine the balsamic vinegar and honey or maple syrup. Cook the mixture, stirring occasionally, until it has reduced by half and has a thicker, syrupy consistency. This should take about 5-7 minutes.

5. Once the Brussels sprouts are done roasting, transfer them to a serving dish and drizzle the balsamic glaze on top. Gently toss the sprouts to coat them evenly with the glaze.

6. If desired, add the crumbled bacon to the brussel sprouts and enjoy!
