Opportunity, yes, to cut some meat
I believe the answer is:
look-in
'opportunity' is the definition.
(thesaurus)
'yes to cut some meat' is the wordplay.
'yes' becomes 'ok' (I've seen this in other clues).
'to cut' indicates putting letters inside.
'some meat' becomes 'loin' (loin is a kind of meat**).
'ok' placed inside 'loin' is 'LOOK-IN'.
(Other definitions for look-in that I've seen before include "Make a short visit of visual sort?" , "Chance of success" , "Watch TV (colloq.)" .)
