Clean potatoes and cut into bite size chunks. Steam potatoes until tender, approximately 20 minutes. When finished, place in large bowl and allow to cool.
When potatoes are cool, add red onion and red pepper to bowl. Stir to mix and set aside.
In a smaller bowl, mix vegan mayo, white wine vinegar, brown mustard, and spices (EXCEPT paprika). Mix well and fold into potato mixture. Sprinkle with paprika (or, if you like some heat, cayenne pepper) and serve.
