Place all ingredients but olive oil in the food processor and pulse. Scrape down the sides and turn on the processor. Slowly drizzle olive oil in, scraping down sides as needed. Once pesto is complete transfer to a container and drizzle the last 2 tbsp of olive oil on top.
Notes
Pesto saves really well in the freezer. I have never tried freezing in ice cube trays but I do love little mini mason jars.
