Preheat oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3). Wash thyme and dab dry. Peel garlic and chop very finely.
Clean and wash the aubergines and cut them in half lengthwise. Cut the flesh several times up to the skin. Sprinkle the cut surfaces with 2-3 tablespoons of oil, cover with thyme twigs and sprinkle with garlic. Season with salt and pepper.
Fold the halves together again and place them next to each other in an ovenproof dish. Bake in a hot oven for 40-45 minutes until they are soft. Let them cool down.
Remove the flesh of the aubergine from the skin with a spoon and dice finely. Mix with lemon juice, yoghurt and 2 tablespoons of oil. Season to taste with salt and pepper and chill for about 1 hour.
Drain the peppers. Wash and quarter the tomatoes. Cut both into small cubes and fold into the eggplant cubes. Goes well with flat bread.
