Mmmmm. Simple ingredients, simply prepared. Çoban salatasi, Shepherd’s Salad. Found throughout Istanbul on every menu. And why not? Tomatoes, cucumbers, green pepper, scallions, oil, lemon, parsley, salt. (I’ve seen some variations that occasionally include radishes, though that’s not traditional.) OK, this gussied-up version at the Komşu restaurant in the upscale Nişantaşi section of the city featured a bit of pinwheel presentation, but the center attraction -- the simple fresh goodness -- is always still the same. How can you go wrong, especially at this time of year when backyard gardens yield the main ingredients so readily? I’ve had this refreshing salad in restaurants in Turkey, in Turkish restaurants in New Jersey and Massachusetts, and it’s always been simple and sensational. But this evening, dining on an outdoor terrace in the warm Istanbul evening, it was especially good.
