Grandma T (Paul's Mother) as we referred to her made the best warm potato salad. She used plenty of red onion, parsley, mustard seeds, bacon and potatoes and dressed it with vinegar and a bit of sugar. She loved serving it warm as a side when she had to feed many. On a cold day, it sure does satisfy. Stock up on potatoes and onions to have on hand for making a warm German Potato salad.
