Put all the ingredients, apart from the pastry and egg, into a food processor and roughly chop.
Roll out the pastry and cut into 8cm rounds. Pile the trimmings together, roll out again and repeat.
Put 1 tsp of the olive filling in the middle of each pastry round. Dampen the edges with a little water and pinch the edges to seal - like little Cornish pasties.
Glaze with the eggs and bake for 10-15 mins until golden brown. Serve hot or cold.
