Hand pies are the most portable and thus perfect to take on a picnic or to fill a lunchbox. The ratio of pastry to filling is quite high for a hand pie, so this recipe makes a lot. You could halve the total quantity, freeze a bunch, or make half the quantity of hand pies and use the remaining filling to make another type of pie. This incredibly delicious recipe can also be used to make a more traditional large chicken pie topped with puff pastry.
