Creating roasted vegetables with bright & crunchy herbed topping is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 425°F (220°C).
2. Prepare the Vegetables: Wash and chop your seasonal vegetables into bite-sized pieces.
3. Season the Vegetables: In a large bowl, toss the chopped vegetables with olive oil, salt, black pepper, garlic powder, and onion powder until evenly coated.
4. Spread on a Baking Sheet: Arrange the seasoned vegetables in a single layer on a baking sheet lined with parchment paper.
5. Roast the Vegetables: Place the baking sheet in the preheated oven and roast for 25-30 minutes, or until the vegetables are tender and slightly caramelized.
6. Prepare the Herbed Topping: While the vegetables are roasting, mix together the breadcrumbs, chopped parsley, basil, thyme, lemon zest, and Parmesan cheese (if using) in a bowl.
7. Add Herbed Topping: Once the vegetables are done roasting, remove them from the oven and sprinkle the herbed topping evenly over the top.
8. Return to the Oven: Place the baking sheet back in the oven and roast for an additional 5-7 minutes, or until the topping is golden brown and crunchy.
9. Serve Hot: Remove from the oven and let cool slightly before serving.
