Penne Arrabbiata

This is perfect for a 20-minute lunch break on a workday.

Onions, tomatoes, garlic, basil, olive oil, chilli flakes, oregano...go into a tangy arrabiata. With penne.

I know, strictly speaking, onions don't go into an arrabbiata, but I dodged the arrabbiata police. Follow your heart, not the recipe. I feel onion gives more body and mouthfeel to the sauce.
