Wash parsley, shake dry and chop. Drain chickpeas, rinse briefly and drain. Peel onions and garlic and chop finely. Finely mash the chickpeas, 1 onion, 2 garlic cloves and parsley.
Mix with egg yolk, breadcrumbs and flour, season with 1 teaspoon of salt and 1 pinch of cumin, coriander, cinnamon and cayenne pepper and chill. Clean, wash and cut the aubergine into pieces. Heat the oil in a pot.
Sauté the eggplant in it. Add 1 onion and 1 clove of garlic, fry and deglaze with tomatoes. Chop the tomatoes slightly. Bring to the boil, stir in broth. Season to taste with pepper and a little salt. Heat frying oil in a high pot to approx. 180 °C.
For the yoghurt sauce, wash mint, shake dry and, except for a little to garnish, pluck leaves from the stems and cut into fine strips. Mix yoghurt, milk and mint, season with salt and pepper.
Form about 12 meatballs from the falafel mixture. Bake in hot frying fat in portions for 4-5 minutes until golden brown. Drain on kitchen paper. Arrange the falafel meatballs in tomato and eggplant vegetables.
Add mint yoghurt. Flatbread tastes good with it.
