Here's a loin idea I do every once in a while and is really good.
Season a loin with salt, pepper and maybe a little garlic, cook to 140+, Wrap in foil along with a 1/2# package of sliced mushrooms and a generous spritzing of apple juice. Cook another couple of hours in the foil (usually to 180). I know this seems over done for a loin, but it begins to become fall apart tender at this point.
Carefully open the foil and reserve the juices. Allow to rest, slice or chunk as you best you can and serve along with the mushrooms and juices.
Makes great sandwiches with a nice slice of swiss or other cheese. Very much like a pork version of a mushroom swiss burger.
