Creep off for something to eat (5)
I believe the answer is:
crepe
'something to eat' is the definition.
(crepe is a kind of food)
'creep off' is the wordplay.
'off' indicates an anagram.
'creep' is an anagram of 'CREPE'.
'for' acts as a link.
(Other definitions for crepe that I've seen before include "White fat" , "Crinkled fabric - black armband - thin pancake" , "Crinkled paper or fabric" , "Thin wrinkled fabric" , "Finely wrinkled fabric" .)
