Add all of the ingredients except for the olive oil to a food processor. Pulse 5 to 10 times, or until the ingredients are roughly chopped
Turn the food processor on and slowly stream the olive oil through the opening at the top.
Taste the pesto for flavor and add more sea salt, vinegar, or garlic to taste.
Use immediately or transfer to a sealable container and refrigerate until ready to use. Pesto will stay fresh for up to 7 days in a sealed container in the refrigerator.
*you can use virtually any type of nut or seed in this pesto to replace the pistachios if desired. Try walnuts, almonds, pecans, pumpkin seeds, or pine nuts.
**If using raw garlic instead of roasted, start with only 2 large cloves and add more if you desire more garlicky flavor
