Put all the ingredients (except the olive oil) in the food processor.
Pour in about half the olive oil and pulse a few times, scrapping down the sides of the food processor bowl.
Drizzle in the rest of the olive oil as you continue pulsing and scrapping down the sides of the bowl, until your sauce is beautifully smooth, thick, and glistening green.
You can store your sauce for up to two weeks in the fridge in a covered glass container - if it lasts that long!
