Prepare a turkey, in a way (5)
I believe the answer is:
stuff
'prepare a turkey in a way' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stuff that I've seen before include "Material; fill full" , "set with unspecified ingredients" , "Material - gorge" , "Material - things" , "Miscellaneous objects" .)
