Cucumber Boats

Using paper towels, mop the cucumber “boats” to remove any moisture. In a bowl, combine the garlic, mint, fish sauce, lime juice, sugar and pepper, stirring until sugar dissolves. Stir in the shredded beef and onion flakes. Spoon this mixture into the cucumber “boats” until they resemble fully loaded barges. Line a platter with lettuce leaves and arrange the “boats” on the sea of leaves. Garnis
