Penne all'Arrabbiata

Fry the onions, garlic and chillies in some olive oil. If you are using chicken or any kind of meat, I would toss it in now, if not continue to the next step

Add the chopped tomatoes and cook on high heat. When the tomatoes start to get soft and mushy and begin to ooze out liquid, turn the heat to low so that it forms a sauce

When the sauce is ready, toss in the cooked penne, and mix well so that the sauce coats the pasta really well. I saved some pasta water and added it in

Add the required amount of salt and pepper and the basil or parsley

Sprinkle some grated parmesan to garnish

Serve hot!
