Boil and slice about five medium red potatoes.     

Cook four or five strips  of bacon.    Take out and cool and crumble.    

In the bacon grease cook a medium onion that has been  sliced.    Caramelize them well with a little brown sugar......probably two tablespoons.    

Add  probably a quarter cup of white vinegar, salt, pepper and white sugar to taste.   

Add the sliced  potatoes back in the skillet and coat with dressing.   Crumble bacon on top.
