Swapping bright green pistachios for Ligurian pine nuts, this pesto gets a Sicilian twist. It can easily be made in a food processor or, if you don't have one, by hand.
Preheat oven to 180°C/350°F. Add the pistachios to a rimmed baking tray and toast in the oven until fragrant and slightly darkened - about 5-7 minutes.
Add the toasted pistachios, garlic and pecorino cheese to the bowl of a food processor (see note 1). Pulse a few times, just until the pistachios and garlic are finely chopped and the cheese is finely grated.
Add the basil and parsley and pulse until mostly broken up - 5-7 times.
With the machine running, slowly stream in the olive oil and mix until emulsified. Taste to adjust for seasoning, adding salt and pepper to taste.
