Set meals? (2,7)
I believe the answer is:
tv dinners
'set meals?' is the definition.
(I've seen this before)
'set meals?' is the wordplay.
'set' becomes 'TV' (TV set).
'meals?' becomes 'dinners' (dinner is a kind of meal).
'tv'+'dinners'='TV DINNERS'
(Other definitions for tv dinners that I've seen before include "set meals?" , "Scoff watching soaps" , "set menu?" , "Easy to do" .)
