Notes
Make-Ahead: You can make this green goddess dressing recipe up to 3 days ahead. You can serve it immediately, but more flavors will develop with time.How to Store: Place in an airtight container in the refrigerator for up to 7 days. This will not freeze.If the dressing breaks, you can try and blend it with 2 teaspoons of Dijon mustard.Feel free to use any oil you’d like, but I recommend a soft, very light virgin olive oil or any other neutral-flavored oil like sunflower oil. You can also blend the oils.Substitute the green onions with chives.Dry herbs will not work in this recipe.
