This German potato salad recipe is one I grew up with. My German grandmother made it often during the warm weather months. The oil and vinegar is a tasty change from other summer salads.
Peel the potatoes, cut in half and cook them until they are done but not mushy. Drain them well and put them aside to cool a bit.
When the potatoes are cool enough to handle, cut them into chunks or thick slices and add them to a large bowl. Chop the onions, dill and parsley. Add it all to the same bowl and season with salt and pepper to your taste.
Heat the oil, vinegar and sugar together. Pour the dressing over the potato mixture. Stir the salad well to combine all the ingredients and let sit for a bit before serving to incorporate all of the flavors.
