Chop the garlic and chilli.
Heat the olive oil in a sauté pan (medium heat) and add the chopped ingredients (garlic/chilli) into the pan.
Sauté for a couple of minutes or until the garlic becomes golden in colour.
When the garlic has turned to golden, add the chopped tomatoes.
Stir for a few seconds.
Season with salt.
Stir again for a few seconds.
Now, cook on medium/low heat for about 20-25 minutes, to reduce the sauce. After this time the suace will be ready.
A few minutes before the arrabbiata sauce is ready, boil your pasta and when the pasta is cooked al dente, drain it and add it into the pan containing the sauce.
Stir for a few seconds to coat the pasta with the sauce. Do this when the pan is still on the heat.
Then, sprinkle with chopped parsley.
Give a quick stir and serve immediately.
