Clean and wash the tomatoes, carve them crosswise and place them in an ovenproof, greased dish. Grate the parmesan. Wash and finely chop the parsley. Mix cheese, parsley, lemon peel and butter and spread on the tomatoes.
Bake the tomatoes in a preheated oven (electric oven: 200 °C/ gas: level 3) for 12-15 minutes. Season pork fillets with salt and pepper. Heat 2 tablespoons of oil in a pan. Fry the pork fillets in it from each side for about 3 minutes.
Take the meat out and keep it warm. Cut bread into slices. Peel garlic and chop finely. Heat the remaining oil in the pan. Add the garlic and fry the bread pieces on both sides.
Arrange tomatoes, pork medallions and garlic bread on a plate. Garnish with lemon and lemon balm.
