Wash and halve the tomatoes, remove the stalk. Roughly dice.
For the dressing, squeeze out the juice of half a lemon and mix with yogurt, cumin and sambal oelek. Roast the sesame seeds in a pan without fat over medium heat for a few minutes until golden brown. Add to the yogurt mixture and season with salt and pepper.
Finally, carefully mix the tomatoes with the dressing and the chopped parsley. Serve as a side salad or as a starter with flatbread.
Tip: If you want, you can add 1/2 glass of black olives (drain, cut in half).
