Looking for a nutritious side dish for your Thanksgiving table? We’ve got it, plus a few tips for perfect preparation. When you roast fall’s bounty of vegetables, be sure to go easy on the oil and keep the oven temperature below 405 degrees if you’re using extra virgin olive oil (it’s the oil’s smoking point). Overheating can break down nutrients, change the flavor and release harmful free radicals. Save the good quality olive oil for salads and pasta dishes, and use lighter, more refined olive oil for roasting.
