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' is an anagram indicator.
'creep' with letters rearranged gives 'CREPE'.
'to get' acts as a 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" .)
