• I use rolled puff pastry fresh or frozen here and there is no wastage of pastry.
• The filling is best spread onto the pastry when chilled so I tend to make it the day before I want to use it.
• Substitute the chicken breasts for left over cooked turkey and ham from Christmas, a perfect way to use leftovers. Add this at point 5 where you add the cooked ham. You could make it vegetarian by adding some more leeks and mushrooms or make a ham and stilton one.
• I make pots of the filling (with no chicken or ham) freeze it and have it to hand to add chicken, cheese, ham etc to when I need a pie.
