Step 1
Heat the oil in a large frying pan over medium heat. Add the onion and cook, stirring, for 2 mins or until onion softens. Add the mince and cook, stirring with a wooden spoon to break up lumps, for 5 mins or until mince is cooked through.
Step 2
Stir in vegetables. Add gravy mix and 3/4 cup (185ml) water and cook, stirring, for 1 min or until liquid reduces slightly. Add tomato sauce and barbecue sauce. Bring to a simmer. Cook, stirring often, for 5 mins or until the mixture thickens slightly. Remove from heat. Cover and set aside for 30 mins to cool.
Step 3
Preheat pie maker. Use a 10.5cm pie maker base cutter to cut 16 discs from 4 pastry sheets. Use a 9.5cm pie maker top cutter to cut 16 discs from the remaining pastry sheets.
Step 4
Place 4 large base pastry discs in the pie maker holes. Spoon 1/4 cup of mince mixture into each pie base. Top with 4 small pastry discs. Lightly press edges to seal. Close the lid. Cook for 8 mins or until the pastry is golden. Repeat with the remaining pastry and mince mixture to make 16 pies. Serve the pies with tomato sauce.
