Flatbreads become stale very quickly, so it’s no surprise that there’s an array of Arab dishes made with crumbled-up pitas. This is my favorite destination for them (I love any dish where bread is soaked with salad dressing). You can use whatever greens look good in your market -- arugula, watercress, purslane, and cut-up leaves of romaine lettuce are all acceptable. The Middle Eastern spice sumac is available in Middle Eastern markets; the salad will still be delicious if you don’t include it.
