Roasted Root Vegetables with Walnut Pesto
Carrots and parsnips have a slight sweetness that balances the bite of the Brussels sprouts and turnips. Toss the vegetables with fresh-tasting pesto after they roast to brighten both the flavor and color. You can prepare the pesto up to one day ahead and refrigerate it in an airtight container. If making it ahead, let the pesto stand, covered, at room temperature for about 15 minutes before tossing with the vegetable mixture.
