Preheat the oven to 200C
Remove the skin from the chicken pieces.
Place chicken into a roasting dish, which has been sprayed with some one-cal oil spray
Add the vegetables around the chicken.
Add the garlic cloves and rosemary sprigs, tucking them into any gaps.
Spray everything lightly with the oil spray.
Sprinkle over the dried thyme and lemon juice and twist over some black pepper.
Add a splash of water to prevent sticking.
Place the pan in the oven and cook for 30 - 40 minutes, turning the chicken and vegetables from time to time.
When the chicken is cooked (the juices run clear) remove from the oven. Discard the rosemary sprigs and squeeze out the garlic from their skins.
Divide between four plates and serve.
