Preheat the oven to 425°F. Line a sheet pan with aluminum foil for easy cleanup.
In a small bowl, whisk together the dried dill, dried parsley, garlic powder, onion powder, salt, and black pepper.
Place the carrots, cauliflower, broccoli, and green beans in a large bowl. Drizzle with olive oil and toss to coat. Sprinkle with the seasoning mixture and toss again.
Spread the seasoned vegetables in a single layer on the prepared sheet pan. Roast for 20 minutes, until tender and lightly browned at the edges.
Transfer to a serving dish and sprinkle with fresh parsley. Serve warm.
