Sicily is known for its pistachios, so it’s no surprise that the colorful, subtly sweet nuts feature heavily in the region's desserts and savory dishes. This recipe is our take on a pistachio- and tomato-dressed pasta that we tasted in Siracusa. With lemon zest and mint as accent ingredients, the flavors are fresh and bright. Just about any variety of pasta worked well, but we particularly liked long strands, such as linguine and spaghetti.
