Preheat oven to 425F. Lightly coat a large rimmed 15×10-inch roasting pan with nonstick cooking spray.
Place all the ingredients (except the brown sugar) on the prepared baking sheet. Toss to coat.
Transfer to the oven and roast for 20 minutes.
Sprinkle with the brown sugar, gently toss, and return to the oven for another 10 minutes or until the vegetables are charred and tender.
Serve and enjoy!
