Transport about half of veal where it's sliced? (7)
I believe the answer is:
carvery
'where it's sliced?' is the definition.
The definition suggests a singular noun which matches the answer.
'transport about half of veal' is the wordplay.
'transport' becomes 'carry' (synonyms).
'about' means one lot of letters goes inside another.
'half of' suggests halving the letters.
'veal' halved is 've'.
'carry' placed around 've' is 'CARVERY'.
(Other definitions for carvery that I've seen before include "Buffet with roasts" , "Buffet serving sliced meat" , "where the main course is meat" , "food outlet" , "cafe" .)
