Scoffed portion of meat enthusiastically (5)
I believe the answer is:
eaten
'scoffed' is the definition.
(I've seen this before)
'portion of meat enthusiastically' is the wordplay.
'portion of' indicates a hidden word.
'EATEN' is hidden in the letters of 'meat enthusiastically'.
(Other definitions for eaten that I've seen before include "absorbed in the system" , "having been fed?" , "Taken into the body as food" , "dined" , "Got" .)
