Olives make all kinds of Italian food, just a little more Italian. If you love olives and decide to use them in this recipe. Make sure to chop the olives in the desired shape (preferable rings) and then toss them with the cooked pasta. If you're going to be using olives, however, you probably won't require any extra salt. This is because Kalamata and green olives already bring extra salty and tanginess to any recipe.
