Manage to peel stuff, which could make an ingredient eating dinner (7)
I believe the answer is:
anagram
'which could make an ingredient eating dinner' is the definition.
('ingredient' is an anagram of 'eating dinner')
'manage to peel stuff' is the wordplay.
'to peel' indicates the central letters (I've seen 'peeled' mean this (outer letters are peeled off)).
'stuff' becomes 'ram' (ram can mean to stuff or push).
The centre of 'manage' is 'anag'.
'anag'+'ram'='ANAGRAM'
(Other definitions for anagram that I've seen before include "Nag a ram (anag)" , ""Schoolmaster" is of "the classroom", for example" , "Gelding can be niggled by this" , "Word made by rearranging the letters of another" , "There's confusion among characters" .)
