Yes. I like to use dried herbs for convenience and to maximize how long the dip will last, but you can substitute fresh herbs. Just note that you will need to use three times the amount since fresh herbs are not as potent as dried herbs. I also suggest adding the fresh herbs to the blender with the other ingredients to ensure they blend in. This will also turn the dip a vibrant green colour. If you use fresh herbs, the dip will last about 4-5 days.
