Cod with Pesto and Cheese Topping

This is a WeightWatchers recipe that I photocopied out of a friends book ages and ages ago and it's been sat in my file. I suddenly seemed to have the right ingredients all at the same time gave it a go. It was really delicious and tasty. I was a bit dubious about the mushrooms but they work in this dish. I served it over pasta.

Cod with Pesto and Cheese Topping (from WeightWatchers Member's Favourites)
(Serves 4)
(5 WW ProPoints per serving)

2 tsp  oil
1 onion, finely sliced
175g mushrooms, finely sliced
1 courgette, diced
400g chopped tomatoes
1 tbsp pesto
675g skinless cod fillet
50g half fat cheddar, grated
salt and pepper

Preheat the oven to 180C. Heat the oil in a saucepan and fry the onion over a medium heat for 5 mins until softened.

Add the mushroom and courgette and continue to cook for another 5 mins, stirring every so often until the veg are soft.

Pour in the chopped tomatoes, add the pesto and stir into the veg. Continue to cook over a medium heat for 5 mins until the sauce has thickened.

Place the fish in a large ovenproof dish. Spoon the veg mixture over the fish making sure you cover the fish. Sprinkle the cheese over the top.

Bake in the oven for 25 mins until the fish is cooked and cheese golden and melted.
