Preheat the oven to 220°C/200°C fan. Place the chicken on an oiled roasting pan. Place the chicken skin side up on the pan and cook in the oven for 20 minutes until the skin browns. Reduce heat to 180°C/160°C fan and cook for a further 15 minutes, or until the juices run clear when probed.
Meanwhile, preheat a griddle or BBQ grill to medium-high. Toss the vegetables in the balsamic vinegar, honey, oil, thyme and season with salt and pepper. Place them on the heat and grill each side for five minutes or until golden and beginning to soften.
Let the chicken rest for 5-10 minutes. Carve and serve with the vegetables.
