The cranberry and spice mixture will freeze just fine. I'm not sure how the apples will hold up. They might lose their texture, and I think the nuts would do the same. If you think you won't eat all of it and want to freeze it, I would only add the apples and nuts just to part of the batch. Freeze the remaining cranberry and spice mixture. When you are ready to serve that, thaw and add fresh apples and nuts.
