Lightly rub the scallops with olive oil and sprinkle with salt. Grill lightly on medium hot grill, turning as needed, do not burn or char, for about 2 to 3 minutes.
Meanwhile place lettuces, Gorgonzola cheese, cranberries, dressing, salt and pepper in a mixing bowl. Toss gently with tongs. Arrange the greens on a salad plate. Arrange scallops around the top and sides of the greens. Garnish with the lemon.
Serves 4 as a first course
