Place the halved Brussel sprouts in a large bowl. Drizzle with the oil and stir to lightly coat the sprouts. Season with salt and pepper. Add the bacon pieces. Stir to blend the ingredients.
Transfer the mixture to a large baking pan sprayed with nonstick spray. Cook for 30-45 minutes until the sprouts darken and slightly char around their edges. During the cooking time, stir the sprouts every 15 minutes. (cooking time will vary based on the size of the sprouts and thickness of the bacon)
Notes
You can substitute frozen Brussels sprouts. However, they will need to be mostly defrosted before preparing the recipe.
