Puttanesca pasta bake

Method

1. Heat a glug of olive oil in a sauté pan or large deep frying pan 
and fry the sliced garlic cloves and chopped red chilli over a low-medium heat for 2 minutes. Stir in the olives, capers, tinned tomatoes, half a 
tin of water and tomato purée. Season with black pepper and a little salt, bring to the boil, 
then simmer over a medium heat for 15 minutes. Heat the oven 
to 200°C/180°C fan/gas 6.
2. Meanwhile, cook the pasta according to the 
pack instructions in a large saucepan of boiling salted water until 
al dente (cooked but with a little bite). Drain, reserving a cup 
of cooking liquid, then stir into the tomato sauce along with 
the tin of drained and flaked tuna and a little 
of the cooking liquid to coat the pasta.
3. Pour the mixture into a 1.2 litre ovenproof baking dish and scatter over the grated mozzarella. Bake for 20 minutes until piping hot and the topping is golden. Serve the pasta bake scattered with fresh basil leaves and a side salad, if you like.
