Combine all the salad ingredients together in a bowl and fress with the lemon juice, extra virgin olive oil and salt & pepper.
For the yoghurt topping
Whisk together all the yoghurt topping ingredients until smooth
Finishing the salad
Decant the salad onto a platter into a bowl. Spoon over some of the yoghurt topping and, if using, sprinkle over some Aleppo pepper or sumac. Drizzle as generously as you're feeling with more extra virgin olive oil.
