Carve a large slice of meat (4)
I believe the answer is:
veal
'meat' is the definition.
(I know that veal is a type of meat)
'carve a large slice' is the wordplay.
'slice' indicates a hidden word.
'VEAL' is hidden within 'carve a large'.
'of' is the link.
(Other definitions for veal that I've seen before include "Calf meat" , "White meat" , "Calf flesh" , "what the meat course may be" , "Type of meat" .)
