1Fry bacon...set aside to drain. Boil potatoes until tender..but not mushy.This is a hot salad. You just want them tender. In the same pan from the bacon,saute the onion until tender but not too brown just translucent about 1-2 mins.Add the celery. Continue for about 1-2 more mins.to soften slightly yet be a bit crisp.
2Combine the oil vinegar and sugar in a jar. Season with salt and pepper to taste.....a tsp of mustard or less can be added if you like. It will keep the dressing from separating longer and add more flavor.Dijon is great
3Pour about 1/3 of dressing into onion celery pan and heat to gentle simmer
Cut up warm potatoes and place in a glass bowl.pour warm dressing over...season a bit more with salt and pepper. Toss bacon and fresh parsley gently with all!! Add more dressing as needed or if .....there are leftovers...or you just like a wetter salad.
tip!!! If you want to make ahead...hold back on the bacon and parsley until you are ready to serve...:)
4Reheats well in the microwave partially covered...and at short intervals of a minute at a time..checking and gently stirring in between
