Meat and potato pie

As the mornings get crisp and we know that frost is imminent, this pseudo pie – pastry only on top- is the perfect antidote. This warm and bubbly pub classic hits the spot. For a quicker version, just use store -bought. I love making a big batch so I have a quick reheat dinner for the next couple of days.
