Preheat the pie maker. Butter bread generously and chop into 2ish cm squares. Mix up everything else except blueberries. Divide bread between the 4 pies, sprinkle with blueberries and pour over the egg mix. Close lid and cook until centres are cooked (this will vary depending on your pie maker). If you have a big family pie one, just bung it all in.
To make this a dessert, try swapping the milk for condensed milk, ditching the sugar and calling it bread and butter pudding!
