Arrabbiata sauce is easy to prepare as it is made from ingredients typically used in Italian cuisine. Pour the contents of the jar into a pan and heat it as it is or add a small amount of the cooking water from the pasta. When the pasta is cooked, add it to the pan with the chosen sauce. Mix together and toss over the heat for a little while. Add a little grated parmesan cheese and your Granoro first course dish is ready to serve. Once opened, any leftover product should be kept in the fridge.
