Roast sesame seeds without fat, remove. Boil up just under 1/2 l water, stir in stock. Cover the bulgur and let it swell for 10-20 minutes (or see package instructions). Let cool down
Wash the mint and chop finely, except for a little to garnish. Stir into the yoghurt. Peel the garlic and press it directly into the yoghurt using a garlic press. Season to taste with salt, pepper and lemon juice
Peel the cucumber, quarter it lengthwise and dice it roughly. Wash tomatoes and cut into pieces. Peel and finely dice the onion. Mix everything with bulgur and vinegar. Arrange salad with yoghurt sauce and sprinkle sesame seeds over it. Garnish with remaining mint and possibly lemon wedge. Flatbread tastes good with it
