You probably know this already, but just in case...........with wild turkey, goose and duck breasts you cut them WITH the grain (ie the long way), not against the grain. If you have three turkey breasts left, I suggest you slice one up and do it as teriyaki on the BBQ. This is always a hunt camp/fishing camp crowd pleaser. Strips about 1/8 inch thick, marinade for at least 12 hours, and BBQ no more than 2 minutes per side.
