Preheat an oven to 400 degrees Fahrenheit. Combine all of the ingredients in a medium bowl and toss to coat evenly. Heat a large non-stick skillet over high heat and add the vegetables. Saute and toss the vegetables for 5 minutes, or until they begin to caramelize. Transfer the vegetables to a medium roasting pan and place in the oven. Roast the vegetables for about 25 minutes, or until browned and cooked throughout. Serve warm or room temperature.
