Peel the onions and cut into small cubes. Wash and chop the parsley.
Put the minced meat with the onion and parsley in a bowl. Add the soaked and squeezed bun and the eggs. Season with salt and pepper and work everything into an even meat dough.
Shape walnut-sized balls with wet hands, turn in flour and then fry all over in hot oil in a hot pan, then continue frying over low heat.
During this time, scald, peel and dice the tomatoes, removing the seeds. Put in the pan and let simmer for a short time. Pour the meat stock, cook the meatballs and tomatoes for about 10 minutes over a low heat. Now season the sauce to taste.
