Let the puff pastry slices thaw a little. Peel and finely chop the onion. Heat the oil in a pan. Brown the onions and minced meat in it. Chop the tomatoes in the tin. Add tomato pieces with the juice and season with salt, pepper and paprika.
Let the minced meat cool down. Clean, wash and slice the aubergine. Sprinkle with salt and let stand for 10 minutes. Lay the puff pastry slices on top of each other and roll out into a circle (approx. 30 cm Ø).
Grease an ovenproof casserole dish and line it with the pastry sheet. Press the rim firmly. Dab aubergine slices dry with kitchen paper. Layer minced meat and aubergines in the dish. Bake in a preheated oven (electric: 200 °C/ gas: level 3) for 25-30 minutes.
Wash the parsley and pluck into pieces. Sprinkle casserole with parsley and coloured pepper. Serve with a cold yoghurt sauce.
