Clean and wash the zucchini and cut or slice into wafer-thin slices. Peppers clean, wash and cut into very small cubes. Peel garlic and chop finely. Mix vinegar, some salt and pepper well, add oil.
Arrange yellow and green zucchini alternately on plates. Sprinkle with diced peppers and garlic. Drizzle the vinaigrette over the zucchini carpaccio and leave to soak for about 15 minutes. Slice parmesan into fine curls and sprinkle over the carpaccio.
Garnish with the basil and serve sprinkled with the coarse pepper.
