Soak bread in cold water. Peel and finely chop the onions. Halve the chillies, cut lengthwise, remove the seeds and wash the pods. Dice 2 pods very finely.
Knead minced meat, squeezed bread, egg, half of the onions and chilli. Season with salt and pepper. Form 8 meatballs from the minced dough. Heat 3 tablespoons of oil in a pan. Fry the meatballs in it for about 10 minutes, turning from time to time.
In the meantime, clean and wash the spring onions and cut the leek into pieces. Heat the fat in a pot. Sauté the leek pieces for 5 minutes. Drain the corn and add. Season to taste with salt and pepper.
Dice the white spring onion shafts and sauté in the remaining oil. Add the tomatoes and bring to the boil. Season to taste with salt and pepper. Cut remaining chilli pepper into fine rings. Arrange 2 meatballs each with the vegetables and some sauce on a plate.
Sprinkle chilli rings over the meatballs. Garnish with parsley. Sprinkle the rest of the sauce with coarse pepper and serve extra.
