Get yourself a pressure cooker. Whatever the frozen mystery meat turns out to be, pop it in the cooker and let it rip. Fork tender in no time.
I still remember the time I took what I thought was a beef shoulder roast out of the freezer. Popped it in the cooker and when it was done I discovered it was really a prime rib roast I was saving!
Expensive lesson but it turned out fine in the pressure cooker anyway. Meat does tend to shrink up some however.
Another tip: you really should not try to make cookies on the floor.
Sounds like a good holiday - more memories made and that is good.
