Add all ingredients to a blender or food processor.
Blend until smooth and creamy.
If the dressing is too thick, add more water a tablespoon at a time until desired consistency.
Store in an airtight jar in the fridge for up to 7 days.
Notes
For a nut-free version, use sunflower seed butter. Add a pinch of cayenne or smoked paprika for a spicy kick. Shake well before using if dressing separates in the fridge.
