A cold cut (6)
I believe the answer is:
salami
'a cold cut' is the definition.
(I know that salami is a type of cold cut)
This is all the clue.
(Other definitions for salami that I've seen before include "Italian garlic sausage" , "meat product" , "Slim, graceful" , "Highly-spiced sausage" , "Highly-seasonal sausage" .)
