Preparation:
Cut each thigh into 4 pieces. Place the pieces in a bowl together with truffled oil, balsamic vinegar, salt and pepper, and marinate for about 15 minutes. Grill the thighs, either on a barbecue or in a steak pan. Cut each of the red chicory heads in two, then slice and dress with extra virgin olive oil, lemon juice, salt and pepper.
