In my opinion, the dry sherry is the key to the flavor in this dish. If you don’t have it or want it see notes for substitutes.
I used about 3 cups of leftover turkey.
Substitutes for dry sherry: cream sherry, dry vermouth, white wine, Madeira, or 2 tbs apple juice plus 2 tbs apple cider vinegar.
Or just use more chicken broth…..
