Start by putting a pan of water on the hob, add a generous pinch of sea salt and bring the water to a rolling boil. Once boiling, add the pasta and cook as per the instructions on your pasta packet. Once cooked drain and leave to one side.
Roughly slice the tomatoes and olives. Then place a frying pan over a low-medium heat, add the sardines, including their oil and gently fry.
Put a large pan on the heat, add the sardines, including the oil and begin to heat through.
Add the tomatoes and gently fry for a couple of minutes, stirring occasionally. Add the passata and bring the pan to a simmer. Once the sauce has reduced by half, this should only take around 5-8 minutes, add the chopped olives and cook for further 3 minutes.
To the pan add the drained pasta, stir through, and then add the chopped parsley.
Finally, drizzle with a little good quality extra virgin olive oil and grate some hard cheese such as parmesan or pecorino over the top.
