Instructions
Combine the parsley, pine nuts, cheese, garlic, and salt in a food processor and pulse a few times to finely chop. Scrape down the sides of the bowl as needed, and continue pulsing for a few seconds more.
While the machine is running, begin drizzling in the olive oil and pulse just until combined to fully incorporate the oil, about 20 to 30 seconds. Add more olive oil for a smoother pesto. Use immediately or transfer to an airtight container and refrigerate to store.
