Uses for meat that has been in the freezer for 2 years?
It's perfectly safe, even if not a perfect texture, so I'd cook it and eat it. The only question is how.

I suggest that you first mince or finely chop it (even in a food processor) then brown it and cook it in a sauce. Chilli would work well, or curry, or pasta sauce (perhaps in a lasagne). If just cut up small, risotto is another option. These are just examples of what I would do. I've done this quite a lot with meat that I've cooked and frozen, less often with raw meat but still successfully. If you're worried about the texture, you may want to spare your nerves by not planning to serve it to guests, but it will be fine.
