Remove the stems from the cilantro and parsley. I usually just cut just above the tie and don’t go to the trouble of stripping the leaves from individual stems.
Add all of the ingredients except for the olive oil to a food processor, including a few dashes of salt and pepper.
Start food processor, and slowly stream in ⅓ cup of extra virgin olive oil.
Process, stopping to scrape down the sides as necessary, until well combined.
Check consistency and add more olive oil, if necessary (see notes). You should have a sort of pepito pesto paste at this point.
Use immediately or refrigerate until ready to use.
Notes
I prefer to leave my pesto chunky - as sort of a pepita pesto paste - until I use it. I find that I can add additional olive oil later on if necessary. But if you prefer a looser consistency, feel free to add more olive oil.Lightly toast the pepitas in a pan over medium heat for 2-3 minutes if you'd like, it adds more nuttiness.
