Leftover Meatloaf and Mashed Potato Salad

As mentioned below, about half the meatloaf was left over, so we just nuked it. It was served with a potato salad that I'd composed the night before, while the brussels sprouts were cooking. Unfortunately, I wasn't watching closely enough and Idahos boil up faster than Yukon golds, so they were a bit too soft. Nonetheless, I added the usual things: mayonnaise, some whole-grain mustard, minced shallots and celery, pepper and salt. The next night I had to add more mayonnaise and mustard, as the softer parts of the potatoes had melded in and formed a sort of mashed potato dressing. Maybe not the ideal potato salad, but hell, this ain't the county fair.
