Heat oven to 450°F. Line a large rimmed sheet pan with foil.
Add the Brussels sprouts, apples, sweet potato, shallots, chicken, and bacon to the pan.
In a small bowl, whisk together the olive oil and red wine vinegar, along with the seasonings.
Drizzle the seasoned oil and vinegar over the ingreidents on the sheet pan, tossing gently with a spatula or wooden spoon.
Transfer the pan to the oven and bake for 25 minutes, checking to make sure the chicken and bacon are cooked completely. If so, remove from the oven and let it rest for five minutes. Otherwise, return to the oven for another 5 minutes and check again.
Distribute everything among four meal prep containers and enjoy throughout the week. If need be, this can be served cold, or heated in the oven or the microwave.
