Clean the beans, wash them and put them aside. Peel potatoes and wash them thoroughly. For the meatballs, soak rolls in water. Peel and finely dice 1 onion. Knead minced meat, egg, squeezed out roll, ketchup, mustard, thyme and onion.
Season vigorously with salt and pepper. Form 8 meatballs from the mince mixture. Cook the potatoes in boiling salted water for about 25 minutes. Heat the oil in a pan and fry the meatballs, possibly in 2 portions on each side, for 5-6 minutes at medium heat.
Put the beans into boiling salted water and cook for about 12 minutes. In the meantime wash parsley, shake dry and chop finely. Peel 3 onions and cut into rings. Heat clarified butter in a small pan and fry the onion rings in it while turning and remove.
Heat milk and butter. Drain the potatoes, mash them with a potato masher and gradually add the milk. Season with nutmeg. Mix onion rings, except for a few for sprinkling, into the potatoes.
Heat herb butter in a frying pan. Drain the beans and turn in the herb butter. Serve the meatball, beans, mashed potatoes with onion rings and parsley sprinkled on plates. Ketchup tastes good with it.
