Boil potatoes until just cooked through, not mushy.
Cut into small bite sized pieces.
Melt butter in skillet and saute onion over medium heat about 5 minutes.
Add potatoes and cook about 3 minutes, stirring occasionally.
Use your own judgment on the amount of each spice.
I cover the potatoes with a thin layer of each, enough so I can actually see the spice and equal amounts of each with the exception of the paprika which I go a little heavy on and the salt which I go lighter on.
