If you want to meal prep the salad, I recommend preparing salad jars according to the method written above. It would keep for 4-5 days in the refrigerator. Store the pita bread in a separate airtight container at room temperature or in the fridge until just before serving. The Fattoush dressing can also be prepared and stored in a jar in the fridge for up to a month. The tossed salad (minus the pita) can be stored in an airtight container in the fridge for an additional day. But will become soggy after about 24 hours.
