Preheat the oven to 400°F (200°C).
Wash and cut the veggies into bite-sized pieces.
In a small bowl, whisk together the olive oil, balsamic vinegar, and maple syrup.
Pour the mixture over the veggies and toss to coat evenly.
Season with salt and pepper to taste.
Spread the veggies out in a single layer on a baking sheet.
Roast in the oven for 20-30 minutes or until the veggies are tender and golden brown, stirring once or twice during cooking.
Serve hot as a side dish or enjoy as a vegetarian main course.
