Shellfish gratin

Instructions

1 Preheat oven to 200°C. Heat a frying pan and add olive oil. Gently fry onion, cover and cook for a couple of minutes. Add mushrooms and asparagus. Stir through to cook for 3 more minutes. Set aside.

2 To make white sauce, place a small saucepan over a low heat and add spread to melt. Then add flour and pepper. Cook for 1 minute until bubbling. Increase heat to medium and gradually pour in milk (half a cup at a time), stirring as you go to prevent lumps. Simmer. Stir until sauce is thick and smooth. Add half the parmesan and stir until melted.

3 Lightly spray an ovenproof baking dish with oil. Layer a few vegetables on the base, top with a layer of shellfish then pasta then vegetables (reserve some asparagus and mushrooms for top). Drizzle over a little white sauce then add the remaining vegetables.

4 Pour over the remaining sauce then sprinkle with the remaining parmesan. Place high in a hot oven to bake for 20-25 minutes.
