Use 2 cups of frozen mixed vegetables instead of mushrooms, carrot and green capsicum.
To freeze, allow mince to cool then spoon into a large snap-lock bag. Seal. Flatten bag for quicker defrosting. Freeze for up to 3 months. Thaw in refridgerator overnight. Transfer savoury mince to a large saucepan. Reheat, stirring over medium-high heat, adding extra stock if necessary. Cook wedges as directed.
