Cook the bacon and save the drippings.
In a medium pot, cook the potatoes in 1 inch of boiling salted water, covered. Cook until tender. Drain,pare and slice the potatoes -- set aside
While the potatoes are cooking, make the dressing by heating up the bacon drippings, vinegar, onion, and salt. You may add a few dashes of paprika to this mixture if you like.
In a large bowl, combine the hot potato slices, the dressing and the bacon -- toss gently as to not break the potato slices.
Serve immediately. This amount will make about 6 servings.
