Using a food processor, pulse the walnuts until they are nice and small

Add in your basil and pulse a few times to break it down

Add in your garlic and pulse a few times until everything is incorporated

Now turn your food processor on low and slowly drizzle in your oil so it can all get evenly mixed

You may need to stop and scrape the sides a few times

Once done, season with salt and pepper to your taste liking and enjoy
