I froze a spare chicken breast raw, to save for my daughter (I very rarely eat meat, she has a bit more, but they come in packs of 2). I noticed it's got visible freezer burn. I refuse to waste it, so I'm going to eat it myself; after all, it's perfectly safe.
Normally I'd stir-fry chicken breast with veg, and add a sauce. I know from past experience that it can end up rather tough in that case. Can I do better?
