Wash the zucchini and trim off the top and the bottom portion.
Slice the zucchini on the horizontal axis as thinly as possible, trying to create 1/8 inch thick slices.
In a heavy skillet, or a stove top grill or over a wood-fired grill, toast the zucchini slices until they begin to grill, turn brown but not too charred. Each piece should become soft and very pliable.
In a large dish or bowl, add the cooked zucchiniand add four tablespoons of oil, and the 2 teaspoons of vinegar. Add salt and pepper flake to taste.
While the zucchini marinate, prepare the Bruschetta Classica slices.
After 5 minutes of marinating, arrange the zucchini on the bread and garnish with salt, pepper flake and oil if needed.
