Creep off to get some food (5)
I believe the answer is:
crepe
'some food' is the definition.
(crepe is a kind of food)
'creep off' is the wordplay.
'off' indicates an anagram.
'creep' is an anagram of 'CREPE'.
'to get' is the link.
(Other definitions for crepe that I've seen before include "Crinkly fabric and French pancake" , "Finely wrinkled fabric" , "French dish" , "Crinkled fabric - black armband - thin pancake" , "One fabric" .)
