I think the nuking is a great idea. I've seen a lot of hot dishes that call for mayonnaise. Miracle Whip is what I keep on hand, and that works too.
I do wonder what it will do to the hard-boiled eggs. I will be interested to hear how it turns out.
I've started nuking whole potatoes for potato salad and mashed potatoes too. It's just so much easier for me, physically. Once they're done, I let them cool a while, and the skins come right off. I've really been pleased with the results, and there's one less pot to wash.
Anyway, getting to the point...Kim thought the potatoes were a little firm in the batch I made the other night. They were done, though, and well-seasoned, as I always make my potato salad a day ahead of time. It makes so much difference when you give the potatoes time to soak up the seasoning! (Pasta salad is the same way.)
I had another suggestion for you, and that was to turn your potato salad into a hot dish. Add a little bacon and cheddar cheese, and I'll bet it would be delicious!
