Spicy tomato and mackerel pasta

Method

1. Bring a large pan of water to the boil and add a good pinch of salt. Meanwhile, heat 1 tbsp oil in a large frying pan, then add the onion. Fry over a medium heat for 5-8 minutes until it starts to soften and colour.
2. Add the sauce to the onion and simmer for 5 minutes. Stir in the mackerel and simmer for 5 minutes more.
3. While the sauce is simmering, drop the pasta into the boiling water and cook according to the pack instructions. Drain the pasta quickly (a bit of remaining pasta water will help loosen the sauce), then stir into the sauce. Scatter with the basil, then serve straightaway.
