For the meatballs peel 1 onion and cut it into fine cubes. Wash the mint, shake dry and, except for something to garnish, pluck the leaves from the stalks and chop them. Knead minced meat, onion, egg, breadcrumbs and mint.
Season with salt, pepper, cinnamon and coriander. Form 16 balls from the mince mixture. Heat 1 tablespoon of oil in a pan. Fry the balls for about 8 minutes while turning. Meanwhile peel the remaining onion and cut into cubes.
