Wash the meat, dab dry and pat flat. Season with salt and pepper. Heat oil in a pan. Fry the meat for about 4 minutes on each side and remove. Wash the tomatoes, grate dry and cut into 4 slices.
Drain the mozzarella and cut into 8 slices. Wash the basil, shake dry and pluck the leaves from the stalks. Halve the olives. Spread the tomato slices and olives on the cutlets, place 2 basil leaves on each and cover with 2 slices of mozzarella.
Bake under the preheated grill until the cheese has melted. Arrange on plates, sprinkle with pepper and garnish with remaining basil leaves.
