Remarks
An idea to try: a complete pitta meal with a savoury course as described above, and a sweet course with small diced fruit, custard cream or whipped cream, melted chocolate, etc... For the sweet part, it's a good idea to dust the pittas with caster sugar before puting them to the oven, so that they caramelize slightly.
