Add all ingredients except oil to a food processor and pulse until chopped.
Once chopped, turn the food processor on and stream the oil through the opening in the top. I like my pesto sauce thick, but you can add more oil to your personal taste.
Continue processing until desired texture is reached. Taste pesto for flavor and add more sea salt or nutritional yeast.
Notes
*Replace the nutritional yeast and cider vinegar with 1 cup of grated parmesan cheese if you do dairy. If you go this route, increase the amount of avocado oil to 2/3 cup or 1 cup.**Use more avocado oil for thinner, saucier consistency
