This nutritious dish is the perfect one-pan weeknight meal. Pour a glass of Martha's Chard and it doesn't get any better than this.
1. Preheat oven to 450 degrees. Let chicken stand at room temperature 1 hour. Pat dry, then rub with oil and season with salt and pepper. Place on a rimmed baking sheet.
2. Toss together sweet potatoes, cauliflower, pancetta, rosemary, and oil; season with salt and pepper. Spread around chicken (they won't be in a single layer). Roast 25 minutes; remove from oven.
3. Turn vegetables and add capers. Return to oven and roast until a thermometer inserted in thickest part of chicken thigh (without touching bone) registers 165 degrees, 25 to 30 minutes more. Let chicken rest 10 minutes. Meanwhile, toss vegetables with pan juices and return to oven, if additional browning is desired, 5 minutes. Serve chicken with vegetables.
