I overbaked some pork chops by about ten minutes the other day. Instead of leaving them uneaten and having to eventually throw them out, I discovered a solution. Cut the chops into small slices and simmer them in some stock, barbecue sauce and a couple of tablespoons of olive oil for maybe 5 minutes. It restored them and they ended up being delicious after!
It seems that when meat becomes dried out, it has lost liquid and fat. You can replace what has been lost by adding some liquid and fat.
