Ingredients
Method
1.Preheat oven to 220°C/200°C fan forced. Place potato and garlic in a large saucepan; cover with cold water. Bring to the boil. Boil for 10 minutes or until tender. Drain; return to pan. Add milk and half the butter; mash until smooth. Season.
2.Meanwhile, drain tuna chunks, reserving brine from can. Melt remaining butter in a large saucepan over moderate heat; remove pan from heat. Add flour; stir until mixture is smooth. Return pan to heat; cook and stir for 1 minute. Slowly stir in reserved tuna brine and extra milk; cook and stir for 3 minutes or until sauce boils and thickens. Add both tuna varieties and mixed vegetables; cook, stirring occasionally, for 5 minutes or until mixture is hot.
3.Spoon fish mixture into a 20cm round (base diameter) x 7cm deep ovenproof dish; top with mashed potato, then sprinkle with breadcrumbs. Drizzle with extra melted butter. Bake for 15 minutes or until golden and bubbling. Serve with salad.
Make ahead: You can make pie up to 4 hours ahead. Cover, then refrigerate. Low fat: Use reduced-fat or skim milk. We used a frozen chunky vegetable mix of cauliflower, broccoli and carrot. Choose a potato variety that’s suitable for mashing.
