Peel and finely dice the onions and garlic. For the sauce, wash parsley, shake dry and chop finely. Wash and coarsely dice the tomatoes. Heat 1 tablespoon of oil in a saucepan. Sauté half of the onions in it.
Stir in 1 tablespoon of tomato paste and sauté. Add tomatoes and 3 tablespoons sherry, bring to the boil, cover and simmer for about 15 minutes.
For the meatballs, knead the minced meat, remaining onions, garlic, egg, breadcrumbs, parsley and 1 tablespoon of tomato paste. Season with salt, pepper, 1sp. cumin and 1sp. coriander. Form approx. 24 meatballs.
Heat 2 tablespoons of oil in a frying pan. Fry the meatballs for 8-10 minutes in portions all around.
Season the tomato sauce with salt, pepper, sugar and sherry. Add meatballs to the sauce and braise for another 5-10 minutes. Flatbread tastes good with it.
