Can I remove frost from frozen chicken breasts and re-package?
I'd recommend just cooking them sooner rather than later. If you had to do anything, I'd consider cracking &amp; brushing off the surface ice without thawing them, then vacuum sealing them ... but still try to use them quickly.

If the texture is a little off, or the flavor a little lacking, you can always use the rest in either soup or a casserole, where the texture isn't as much of an issue and there are other flavors to help compensate.
