Preheat the oven to 180°C.
Using a 5 cm round cutter, cut 12 rounds of just thawed pastry and tuck into non-stick 12 cup mini-muffin pan, making sure it is well pressed down.
Place muffin pan into the oven and bake for 15 minutes or until pastry is lightly coloured.
Remove from oven, and press down raised portion.
Return to oven and cook for a further few minutes until pastry base dries out a little while you prepare the filling.
Beat together the egg and milk, then stir in all remaining ingredients. Using a tablespoon carefully fill each pastry case almost to the top.
Return to the oven and bake for approximately 15 minutes or until filling is just firm. Serve warm.
