Put the lid on the food processor and begin turn on the machine. Stream in the olive oil into the pesto. The pesto should be processed after 1-2 minutes.
Open the lid and scrape the inside of the food processor bowl to ensure all the greens and garlic have been mixed in. Pulse a few additional times, if needed.
Transfer the pesto to a serving dish, and enjoy on pasta, homemade pizza, or as a dip for bread.
