Step 1
First pre-heat your oven to 180*c / gas mark 5.
Step 2
Gently melt the butter in a saucepan and then stir in the flour.
Step 3
Over a low heat, slowly add the warmed milk, a little at a time. Make sure to stir continuously, until all the milk is used and you have a smooth white sauce (you may find that using a whisk achieves the best results).Next, stir in the cheese, peas, spring onions and corn.
Step 4
Season with a little salt and milled pepper and remove from the heat.
Step 5
Then tip the cooked penne pasta into a small oven dish, open the tuna and flake it over the pasta. Pour over the cheese and vegetable sauce, smoothing off the top.
Step 6
Finally, scatter over the course breadcrumbs, sprinkle with parsley and bake for 15 to 20 minutes.
