If you wish to toast the pine nuts, add them to a skillet over medium-high heat, and watch them carefully. After a few minutes, they will start to brown. Toss them often until they're lightly golden/browned on both sides. This whole process only takes about 5-10 minutes.
Prep your other ingredients and add everything to the bowl of a food processor except for the olive oil.
Pulse until everything is combined, then slowly drizzle the oil in while the motor is running on "low". Stop to scrape down the sides and continue processing until there's no large pieces of pine nuts.
Transfer to a jar and store in the fridge for up to a week. Great with pasta (try my chicken pesto pasta salad if you're interested).
You can skip toasting the pine nuts if you wish.
Customizations: I encourage you to add more garlic, oil, or even red pepper flakes if you want it to be spicy. Play with the recipe until it tastes exactly how you want it. :)
This is my beloved Kitchen Aid food processor that I used to make this pesto.
