Battered dish? He loathed it on toast (4-2-3-4)
I believe the answer is:
toad-in-the-hole
'battered dish?' is the definition.
(sausages baked in batter)
'he loathed it on toast' is the wordplay.
'toast' indicates anagramming the letters (toast can mean damaged or broken).
'he'+'loathed'+'it'+'on'='heloathediton'
'heloathediton' anagrammed gives 'TOAD-IN-THE-HOLE'.
(Other definitions for toad-in-the-hole that I've seen before include "Batter pudding containing sausages" , "Battered sausage" , "Sausages and batter dish" , "Bangers and batter" , "Sausage and batter dish" .)
