Preheat your oven to 200^{\circ}\text{C} (400^{\circ}\text{F}).
On a large baking sheet, combine all the chopped vegetables.
Drizzle with olive oil, sprinkle with herbs, salt, and pepper. Toss everything together with your hands until well-coated.
Spread the vegetables in a single layer, ensuring they aren't overcrowded (use two pans if necessary).
Roast for 35-45 minutes, flipping them halfway through, until tender and caramelized at the edges.
