Tuna pasta bake

Cook pasta in a medium saucepan of boiling water for 10 minutes or until al dente. Drain well and set aside.

Preheat oven to 190°C (fan-forced). Spray a 1.25L (5-cup capacity) ovenproof dish with cooking oil spray. Heat margarine in a small non-stick saucepan over a medium heat. Add onion and capsicum and cook, stirring, for 5 minutes or until onion softens.

Add flour to pan and cook, stirring, for 2 minutes. Remove pan from heat and whisk in milk. Return pan to medium heat and cook, stirring, for a further 1 minute or until sauce thickens. Reduce heat to low and simmer for 1 minute.

Add pasta, asparagus, beans, tuna and half the cheese to the pan, stirring until well combined. Transfer to an ovenproof serving dish. Combine remaining cheese, parsley and breadcrumbs in a small bowl, then sprinkle over pasta. Bake for 15 minutes or until topping is light golden. Serve.
