½ cup lightly packed parsley
¾ cup walnuts
2 garlic cloves
6 tablespoons olive oil
Kosher salt and freshly ground black pepper
Pinch red pepper flakes, optional
Combine the cilantro, parsley, walnuts and garlic in the bowl of a food processor. Pulse until finely chopped. With the food processor running, drizzle in the olive oil. Season with salt and pepper to taste, and add the red pepper flakes for a bit more kick.
