Preheat the oven to 200 ° C. Season the meat on both sides with salt and pepper and fry in a pan in a little oil on both sides.
In the meantime, cut the tomatoes and mozzarella into as thin slices as possible. Remove the meat from the pan, first evenly cover with the tomatoes and then with the mozzarella. Grind some more pepper over it and place in the oven until the mozzarella has melted and begins to brown.
Finally, spread thinly with pesto and garnish with fresh basil leaves. Ciabatta goes well with this.
