Shred, as cheese (5)
I believe the answer is:
grate
'shred as cheese' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for grate that I've seen before include "Rasp; fire holder" , "Make a harsh rasping sound" , "Firebasket" , "Shred; scrape" , "in which Santa lands?" .)
