re: Food that is difficult to bring back with taste after refrigerating.

Had some leftover steak that was originally cooked a little too long. This particular steak wasn't as thick as the others. Anyway, reheating wouldn't do it any favors.

Used the food processor cheese grater to shred it. Slapped it on the griddle and made cheeseteaks which turned out fantastic.

As to fries, fried chicken/strips/nuggets, fried catfish...convection setting the on oven does wonders.
