That would be the only thing that I would have suggested. Perhaps you can shred it and add it to water and BBQ sauce. If that did not help, I don't think anything will help. I would probably just eat it so you don't waste it.
Smother it in apple sauce and cover it in apple juice. Apples act as a tenderizer. It should help to give the meat a little more moisture and sweetness. Let it sit for an hour or two. Afterwards, drain the apple sauce/apple juice mixture and chop it up in a food processor, just enough for barbecue. Add a little of the reserved sauce/juice mixture and some barbecue sauce, and voila! You should be able to get rid of it fairly fast.
Moistening it is the key. For a more savory flavor, submerging it in beef broth might help. Beer is another option to tenderize the meat so it isn't as tough.
I seem to have a real knack for ruining pork. Thanks for the tips. I froze more than half of it so I may give your suggestion a try when I thaw it out, Poppy.
I ended up cutting some up and putting it into a pot with water and veggies and simmering it for awhile. It made a decent stew but the meat still tasted dry. You know that texture pork gets when it's been overcooked? It is kind of stringy.
The only other thing I can think of that would make it better would be to cook it with butter and onions but that wouldn't exactly make it very good for the diet so I won't be able to do that.
That's what I do when I reheat things. I just add more water to the meat. It really helps a lot so you don't dry it out. Broth, apple sauce like suggested, also works pretty well!
Some stock? Sundays when we have cooked the chicken the night before we heat back in oven with gravy/stock. Depends what you're serving with though I guess?
