Bring a large pan of salted water to the boil and cook the pasta as directed on the pack.

Whilst the pasta is cooking, put the Philadelphia Light in a saucepan with the stock and heat gently until the Philadelphia has melted. Add the tuna and sweetcorn and heat through. Season to taste.

Drain the pasta and toss together with Philadelphia and tuna mixture. Spoon into a warmed oven proof dish and sprinkle with the grated cheese. Place under a preheated grill for a few minutes until golden. Serve immediately.
