This colorful mix of vegetables makes an ideal accompaniment to chicken, beef, fish, or pork, given the roasting brings out the natural sweetness and intense flavors of vegetables. They're a perfect side dish throughout the whole year, whether spring, summer, or fall, but there's just something comforting about having a big dish full of roasted vegetables during the holiday season, particularly next to prime rib, roasted turkey, or baked ham. Another bonus: roasting the vegetables all in one baking sheet saves on cleanup, too, which is always a big plus when you're making a big dinner.
