Prepare the Brussels sprouts by washing them, removing any worn outer leaves, trimming the ends and slicing them in half lengthways.
Place the sprouts onto a baking sheet, drizzle with the oil and season with salt and pepper. Toss gently to coat and roast in the oven for 20 minutes.
Add chunks of the gorgonzola cheese and return to the oven for 3-5 minutes to melt the cheese. Toss to coat the roasted brussels sprouts in the melted cheese and serve.
