Preparation / Directions:
Mince and mash the garlic to a paste with 1/2 teaspoon salt.
In a small bowl whisk together the garlic paste, the lemon juice, the vinegar, and pepper to taste and whisk in the oil. In a shallow baking dish large enough to hold the zucchini in one layer combine the zucchini, halved lengthwise, and the marinade and let the zucchini marinate, covered
and chilled, turning them several times, overnight. Grill the zucchini on
an oiled rack set 5 to 6 inches over glowing coals for 8 minutes and brush
them with some of the marinade. Turn the zucchini, grill them for 6 to 8 minutes, or until they are tender, and transfer them to a work surface. (Alternatively the zucchini may be grilled in a ridged grill pan.) Slice the zucchini diagonally.
