Place all ingredients in a high speed blender or food processor and blend on high until completely smooth. Add water if needed to thin, it will thicken as it chills.
Notes
This dressing doubles as a sauce or dip! When using as a sauce (like on the Mushroom Lentil Tacos) or a dip, you’ll want to keep it on the thicker side. If you're using it as a dressing, keep it thinner by adding more water.
