This fragrant mélange mixes starchy tastes with sweet. The dish is like a stir-fry, only it's done in the oven—a great, no-fuss way to cook a slew of vegetables.
Cooks' note:
Vegetables may be roasted 1 day ahead, then cooled before chilling, covered. Reheat in a 350°F oven until hot, 15 to 20 minutes.
