Say again "Others had food" (7)
I believe the answer is:
restate
'say again' is the definition.
('state' can be a synonym for 'say' so perhaps 'restate' is OK for 'say again')
'others had food' is the wordplay.
'others' becomes 'rest' (eg the rest of a group).
'had food' becomes 'ate' (to eat is to have some food).
'rest'+'ate'='RESTATE'
(Other definitions for restate that I've seen before include "say, in other words" , "Go over" , "say, a different way" , "Once more affirm" .)
