Put all of the ingredients in a food processor and blend for 15 seconds, or until it's pureed. Scrape down the sides of the bowl and mix the pesto for 5 more seconds.
The classic pesto recipe makes 1 cup and will most likely be more than you need for your recipe. Each serving size is 1 T of pesto sauce.
Store in the fridge for up to 5-7 days or in the freezer for up to 3-4 months.
Notes
One serving is 2 Tablespoons of pesto sauce.
Walnuts, almonds, pecans, macadamia nuts, sunflower seeds, and pumpkin seeds are all great substitutes for pine nuts in pesto.
