In a food processor, pulse the garlic & nuts until coarsely chopped.
Add the herbs and again, pulse herbs until chopped (about a minute)
Add the oil slowly. Allow the oil to mix with all ingredients
Stop and scrape down the sides of the bowl.
You may need to add more oil but I find that this amount usually works well.
Add ½ cup cheese (if using) and process to combine.
Season with salt and pepper.
Note:
Sometimes, if I’m going to make a larger batch, with plans to freeze it (in ice cube trays for easy portions later), I’ll leave out the cheese. It’s easy to add fresh grated cheese later.
