Preheat Oven to 400 degrees F. Place trimmed Brussels sprouts, olive oil, kosher salt, and pepper in a large resealable plastic bag. Seal tightly, and shake to coat. Pour onto a baking sheet, and place on center oven rack. Roast in the preheated oven for 20 minutes, stirring brussel sprouts frequently for even coating. Coat with Blueberry Bourbon Pecan Jam and continue roasting another 10 minutes. Serve immediately. Optional, use more Blueberry Bourbon Pecan Jam as a garnish.
