500gfrozen mixed vegetablesI didn't have any so used diced carrots
25gonion gravy powderdidn't have any of that either, substitute tbsp flour and beef stock cube
320gsheet puff pastry
Milk for brushingI used a beaten egg
Preheat the oven to 220C/200C fan/ Gas 7. Grease a 20cm square ovenproof dish (more deviation from me!). Heat the oil in a saucepan over a high heat. Saute the onion for 3 minutes or until softened. Add the mince and cook for 3 minutes or until browned.
Add the vegetables, gravy powder and 125mil hot water. (If using flour add a tbsp of flour and cook, stirring for 3 minutes to cook out the starch, crumble in the stock cube then add the water.) Cook stirring for 3 minutes or until the sauce is thick. Transfer the mixture to the prepared dish and set aside to cool for at least 5 minutes but longer if you can.
Place the pastry sheet over the mince to cover. Tuck the overhanging pastry inwards to form a border around the inside edge of the dish. Score the top of the pastry with a sharp knife. Brush with milk. Bake for 15 minutes or until browned.
Serve the pie with herbed mash or vegetables. I served my pie with slow-cooked Braised Red Cabbage.
