Light a grill or heat a grill pan. Brush the chicken with the remaining 1 tablespoon of oil and season with salt and pepper. Grill over a hot fire or high heat, until golden on the bottom and almost cooked through, about 5 minutes. Turn the chicken and grill for 2 minutes longer, or until cooked through. Transfer to dinner plates, spoon the tomato and goat cheese salad on top and serve.
