Pile the carrots, apples, and onions in the center of a baking sheet. Drizzle with the olive oil, and then sprinkle with the seasonings.

After roasting for about 10 minutes, stir everything and continue to roast for another 8 - 10 minutes.

Notes
Don't overcrowd the pan, or the vegetables will steam.Honeycrisp or Gala apples both work. Keep the skin on.Real maple syrup or pancake syrup both work.Store leftovers covered in the fridge for up to 3 days. Reheat in the microwave.
