Add oil ingredients with the exception of the extra virign olive oil to the bowl of a food processor. Pulse a few times until the mixture has been finely chopped.
While the food processor is running slowly add the extra virgin olive oil. Continue until all of the olive oil is incorporated, being sure to scrape down the sides of the food processor, as needed.
Use immediately or transfer the prepared pesto to an airtight container and store in the refrigerator.
