Wash the tomatoes, dab dry and cut into small cubes. Peel and finely dice the onion. Wash basil, shake dry and cut into fine strips, except for a little to garnish.
Mix tomatoes, onion, basil and 1 tablespoon of olive oil and season with salt and pepper. Clean, wash and pat dry the zucchini. With a peeler, cut lengthwise into thin slices. Cut the escalopes in half crosswise and beat them flat between 2 freezer bags.
Season cutlets with pepper and cover each with 2 slices of zucchini and one slice of ham, fold over and pin. Wash oregano, shake dry and chop. Mix mustard, honey, oregano, some pepper and rape oil.
Spread the ciabatta slices and schnitzel thinly with 3-4 tablespoons of olive oil. Grill the cutlets on the preheated grill, turning them for about 8 minutes. While grilling, sprinkle with salt and brush with the marinade.
Roast the slices of ciabatta on the barbecue, take them down and spread the tomatoes on top. Sprinkle and garnish with basil leaves and serve with the turkey escalopes.
