Bring a large pot of water to the boil and cook the spaghetti until tender with a bite at the centre, about 8 minutes. While this is boiling make your sauce.
Heat a frying pan or saucepan with the oil and add the onions. Sweat down for a few minutes then add the chilli and tomatoes. Cook for 5 minutes.
Drain the pasta, reserving a ladleful of the cooking water. Pour the pasta back into pot and pour in the tomato mixture, salt, pepper, olives and basil. Stir well to combine using tongs. Add the cooking water and mix well.
