Beef good and ready to be eaten (5)
I believe the answer is:
gripe
'beef' is the definition.
(synonyms)
'good and ready to be eaten' is the wordplay.
'good' becomes 'g' (abbreviation).
'and' is a charade indicator (letters next to each other).
'ready to be eaten' becomes 'ripe' (I've seen this in another clue).
'g'+'ripe'='GRIPE'
(Other definitions for gripe that I've seen before include "Grievance" , "carp" , "Keep on complaining" , "beef" , "Complain, grouse" .)
