You can parboil potatoes in a slow cooker by chopping them, covering them with water, seasoning with salt, pepper, and butter, and cooking on low for about 6 hours, or until fork-tender.
Then mix the dressing for your potato salad as you normally would, using mayonnaise, dill, whole-grain mustard, and a splash of red wine vinegar.
You can also make a German-style potato salad with bacon, light dressing, and baby potatoes.
