Preheat the oven to 425 degrees. Then grab a cookie sheet. Spray with cooking spray. Then arrange the chicken in a single layer on the baking sheet. Then arrange the bacon in between the chicken. Then the Brussel sprouts. Then sprinkle the pecans all over the cookie sheet. Arrange the apple slices on top of everything. Then season very well with salt and pepper. Drizzle olive oil over everything and toss. Then finish with drizzling the balsamic vinegar all over. The 1/2 cup will give it a light balsamic flavor. If you love balsamic you can toss the chicken in it before placing it on the cookie sheet. Then drizzle another 1/2 cup like it states in the directions.
