Wash the potatoes thoroughly (if necessary, clean them with a vegetable brush) Cut one side of the potatoes with a knife in a fan shape. Place the potatoes in an ovenproof dish, sprinkle with salt and olive oil.
Bake in the preheated oven (electric oven: 175 °C/ gas: level 2) for 40-45 minutes. In the meantime, clean, wash and cut the beans into pieces. Clean, wash and cut tomatoes crosswise. Sprinkle tomatoes with salt and pepper and place on the baking tray 20 minutes before the end of the baking time.
At the same time sprinkle Parmesan cheese over the potatoes. Put the beans into boiling salted water and cook for about 15 minutes. In the meantime wash the meat and dab dry with kitchen paper. Wash parsley, dab dry and chop finely.
Wash the savory, dab dry and cut into strips. Heat oil in a pan and fry meat for 2-3 minutes on each side. Then season with salt and pepper. Drain the beans and let them drip off on a sieve.
Heat butter in a pot, add beans and savory and turn briefly. Arrange one steak with two slices each of herb butter, beans, tomato and parsley and potatoes (sprinkled with salt to taste) on a plate.
Serve garnished with basil as desired.
