400 degrees whisk together the olive oil, garlic, onion powder, paprika, herb blend and salt and pepper to taste. Pour this over the veggies and toss to coat all. Spread the veggies out evenly as best you can, making sure most of them are touching the bottom of the pan. Roast for 20 minutes then remove from oven and flip them over. Roast for another 20 minutes.
