OK, I should probably not mention this here, but its too good to keep to myself. A few years ago we were cleaning out Mom and Dad's chest freezer but they wouldn't let me throw much away. Well, I found a chicken from Woodwards food floor. (YIKES! They closed down in the early 90s I think) It was shrunken and absolutely petrified. Mom thawed it and they had their personal chef (gift from the kids) make something with it. It grew significantly when it thawed BTW. It was some of the best pot pie I've ever tasted. LOL. Course, they didn't tell me til AFTER I ate it.
I have to admit, if the turkey breast is still sealed well, I'd likely use it. I wouldn't roast it and serve it to guests, but I would probably make a stew, soup, or something saucy with it.
