Preheat your oven (200°C/Fan180°C or Gas Mark 6).
Place 200g pasta into a shallow ovenproof dish and then add the jar of Chicken Tonight White Wine Sauce and the water and place in the oven for 25 minutes.
After 25 minutes stir in the 2 tins of tuna and then sprinkle the grated cheese over the top of the dish and cook for a further 20 minutes until golden.
Great with garlic bread.
