Marcella Hazan, our North Star for all foods Italian, gave us this simple and inspired recipe for pasta, herbs, and tomatoes. Herbaceous and aromatic, it makes for a great light dinner, especially as the weather heats up and the thought of a lush but heavy tomato sauce begins to lose some appeal. Save some leftovers for lunch the next day, served warmed or at room temperature. And feel free to play around with the combination of herbs; just make sure to use the most flavorful tomatoes around, be they big beefsteaks or little cherries. Buon appetito.
