Have you already added liqiud to it? If not you can freeze part (uncooked as long as no liquid or egg has been added) of it in a good zip type bag and use another time. Just add unseasoned stuffing to the part you do use. Although I have to say that it would take a heck of a lot of sage to be too much for me!!!!!

Margo I suggest that you start all over. You can freeze the stuffing that you have already made and maybe the next time you take it out of the freezer you might be able to add something to get ride of the sage taste.
