Preheat oven to 200 degrees C. Line a baking tray with baking paper.
Roll out one sheet of flaky pastry into a oblong, then place it on the prepared baking tray. Spread on the pizza sauce, then place on the meat. Sprinkle on the cheese.
Roll out the other sheet of pastry then slice it into 1-2cm wide strips. Place these over the pizza so they look like mummy bandages. Brush top with beaten egg. Press in olives where you would like the eyes on each slice to be.
Bake in preheated oven for 20 minutes. Allow to cool then slice into smaller rectangle mummy slices.
