Pita bread pieces are essential for fattoush. Either bake, shallow or deep fry your bread pieces. Deep-frying is the traditional method. I like to bake mine so I toss them with some olive oil and bake for 10 minutes in a 400F oven. Sometimes and out of convenience I use pita chips, this usually when I am pressed in time or feel lazy. I have to tell you that using store-bought pitas chips is not your best option as it does not give the same taste.
