Cook the potatoes until fork tender. Drain the water, place in a large bowl and set aside.
Mash the potatoes until desired consistency. I like to leave them a little chunkier. They will breakup more as you stir in the sauce and other ingredients.
Blend together all of the sauce ingredients (cashews, tofu, lemon juice, apple cider vinegar, white vinegar, garlic and onion powder, white miso, and non-dairy milk in a high-speed blender until smooth.
Add the chopped red onions, celery, Dijon mustard, yellow mustard, and dried dill to the large bowl. Stir well and then fold in the sauce.
Sprinkle on smoked paprika and refrigerate until ready to serve. ENJOY!
