Place pine nuts, and garlic in the bowl of a food processor fit with a steel blade. Process for 20 seconds until well chopped.
Add basil, a pinch of salt and pepper. With the processor running slowly add the olive oil through the feed tube. Process until all ingredients are well incorporated. (If it is too thick add more olive oil or even a small dash of veggie stock)
Turn off the processor, add cheese and pulse to combine.
If you don't use right away store with plastic wrap or a thin film of olive oil on top. If air reaches the pesto it will turn brown. You can also store in ice cube trays but be sure to put a bit of oil or plastic wrap on top.
