Heat a large fry pan over medium high heat. Add the bacon and cook stirring occasionally until crisp. Remove the bacon from the pan and drain on paper towels. Pour all but 1 tablespoon of the drippings out of the pan.
Reduce the heat to medium. Add the potatoes, sprouts and onion to the pan. Cook, stirring occasionally until everything is tender and lightly browned. This should take about 15 -20 minutes, but let your eyes and taste be the judge.
