Hackneyed stuff by journalist with complaint — probably canned (6,4)
I believe the answer is:
corned beef
'probably canned' is the definition.
(canned food product)
'hackneyed stuff by journalist with complaint' is the wordplay.
'hackneyed stuff' becomes 'corn' (as in cliched or corny material).
'by' is a charade indicator (letters next to each other).
'journalist' becomes 'ed' (short for editor).
'with' says to put letters next to each other.
'complaint' becomes 'beef' (beef can mean a complaint or objection).
'corn'+'ed'+'beef'='CORNED BEEF'
(Another definition for corned beef that I've seen is " Tinned preserved meat".)
