2. Step 2: Add 2 large peeled and chunked carrots, 2 medium zucchini sliced into 1/2-inch rounds, 1 large red bell pepper cut into 1-inch pieces, and 1 medium red onion cut into wedges to the herb oil mixture. Toss gently to coat all vegetables evenly.

4. Step 4: Remove from oven and transfer to a serving dish. Serve warm as a vibrant side.
