Ready after time for offal (5)
I believe the answer is:
tripe
'offal' is the definition.
(I've seen this before)
'ready after time' is the wordplay.
'ready' becomes 'ripe' (similar in meaning).
'after' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'ripe' put after 't' is 'TRIPE'.
'for' acts as a link.
(Other definitions for tripe that I've seen before include "Rubbish (colloq.)" , "Rubbish, nonsense" , "Something to eat" , "Junk; food" , "Lining of the stomach of a cow as food" .)
