To the food processor add the basil leaves and pine nuts. Pulse a few times to chop.
Add in the nutritional yeast, salt, pepper, and garlic.
Turn the food processor on and let that blend for a few seconds.
Slowly begin to add in the olive oil. Doing this slow ensures that it emulsifies and won't separate later.
Blend for 1 minute until fully combined.
Store in an air tight container for up to 1 week.
