Preheat the oven to 180°C / 350°F / Gas mark 4.
Grease a muffin tray or bun tin lightly with olive oil.
Roll the pastry out until quite thin over a lightly floured surface.
Cut out 10 cm circles for lining a muffin tin or use a cookie cutter for a bun tin.
Line the tray with the pastry circles at the bottoms and re-roll any remaining pastry to make more circles if needed.
Beat the eggs and milk together, add the herbs and pepper.
Sprinkle a little grated cheese in the bottom of each pastry case, then fill with the egg mixture until it nearly reaches the top.
Bake for 15-25 minutes until lightly browned.
These can be served hot or cold and make excellent lunchbox additions.
