Teacher coming back with fish — or meat dish? (7)
I believe the answer is:
rissole
'meat dish?' is the definition.
(I've seen this before)
'teacher coming back with fish' is the wordplay.
'teacher' becomes 'sir' (a male teacher might be addressed as 'sir').
'coming back' says the letters should be written in reverse.
'with' says to put letters next to each other.
'fish' becomes 'sole' (sole is a kind of fish).
'sir' in reverse letter order is 'ris'.
'ris'+'sole'='RISSOLE'
'or' acts as a link.
(Other definitions for rissole that I've seen before include "Losers I find in the chopped meat dish" , "Minced meat or fish deep fried in egg and breadcrumbs" , "Fried and breadcrumbed dish" , "Fried meat dish" , "Lorises (anag)" .)
