Lightly coat the chicken thighs and zucchini with the vinaigrette.
Place chicken and zucchini (cut side down) on the grates, grill 5-7 minutes, then it’s time to flip both. If the chicken sticks, it isn’t ready to flip. Wait another minute and try again.
Continue to cook another 5-7 minutes on the opposite side.
Use a thermometer to make sure the chicken is completely cooked. The internal temperature should be 165F.
Serve with potatoes or rice topped with butter for a balanced meal.
