Have a look – find hidden meat (4)
I believe the answer is:
veal
'meat' is the definition.
(I know that veal is a type of meat)
'have a look find hidden' is the wordplay.
'hidden' indicates a hidden word.
'VEAL' is hidden in the letters of 'have a look find'.
(Other definitions for veal that I've seen before include "Calf's flesh as food" , "Calves' flesh as food" , "Calf meat" , "cuisine" , "White meat" .)
