Fill a large stockpot with water and bring to a boil. Boil the red potatoes until they are fork tender, about 30 minutes. Once the potatoes are cooked, drain and place them in the fridge and cool for about 1 hour or until chilled
Once the potatoes are cooled down, cut them into quarters and place in the same large bowl with the celery, red onion and chives
For the Dressing:
While the potatoes are cooling, combine all of the dressing ingredients into a blender or food processor and process until ultra smooth and creamy. Pour the dressing on top of the potatoes and mix until everything is coated and mixed well.
Keep covered in the fridge for up to three days or serve right way. Enjoy!
