How to store sliced roast turkey
I think what you're asking is almost impossible. Turkey meat, especially the breast, is very dry to begin with. when you cut it, you expose it to air, which doesn't help much. I'd say, leave it uncut if you can; probably wouldn't be a bad idea either to drape it with a cloth (? cheesecloth?) soaked in vinegar, to help protect against nasty little beasties. The vinegar wouldn't leach out onto the turkey to a great extent, I think.
