This is a yummy meat pie often enjoyed in Greece. Of course, every household has their own version - this one's mine. The mushrooms are not traditional at all. They're my way of making the pie even tastier and ensuring my kids enjoy a vegetable they wouldn't otherwise eat. This could be served either as a snack (as eaten as street food here in Greece) or as a main, accompanied by a nice salad. Great to bring along, fully-baked, to a picnic or potluck.
