Knock the schnitzel flat and remove excess fat. Whisk the eggs together and season with salt and pepper. Turn the schnitzel first in flour, then in the egg and finally in the breadcrumbs. Fry in a pan with plenty of clarified butter until golden.
Put the oven on the grill. Line a baking sheet with parchment paper and place the schnitzel on it. First top with ham, then with tomato slices and finally with the cheese. Be generous. If necessary, cut the topping to the size of the schnitzel.
Bake under the grill for about 10 minutes until the cheese has melted.
