This is one of the simplest sauces to make, and one of the most versatile. In Sicily it is known as zogghiu and is believed to be Maltese in origin. It is used to dress grilled fish, meat, and vegetables. It is also delicious spooned onto grilled bread and topped with fresh summer tomatoes. In this version, I’ve added some chopped walnuts to the basic sauce for a little extra body. See the variations that follow for more ways to switch up this spunky, garlicky sauce.

2 lightly packed C. (28 g) fresh mint leaves
2 lightly packed C. (28 g) fresh flat-leaf parsley leaves
2 large cloves garlic, coarsely chopped
1 tsp. fine sea salt
1/4 C. (28 g) coarsely chopped walnuts
3 T. white wine vinegar
3/4 C. (165 g) extra-virgin olive oil, plus more to cover

Place the mint and parsley leaves, garlic, and salt in the bowl of a food processor fitted with the metal blade. Pulse briefly to chop the leaves. Add the nuts and pulse again until everything is coarsely chopped. With the motor running, add the vinegar, 1 T. at a time. Turn off the motor and scrape down the sides of the bowl if necessary. Then, with the motor running, drizzle in the oil. You should end up with a sauce that is somewhat thinner than classic basil pesto, but thick and spoonable nonetheless. Scrape the sauce into a jar or container and top off with a thin layer of olive oil. Store in the refrigerator for up to 1 week, or in the freezer for up to 6 months. If you like, divide the sauce between two or three containers before storing.

Variations
Add 3 or 4 anchovy fillets and 1 T. capers.
Substitute almonds for the walnuts.
Add a handful of finely chopped olives and a generous pinch of dried peperoncini flakes or minced fresh peperoncini.
