Discarded food (6)
I believe the answer is:
scraps
'discarded food' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for scraps that I've seen before include "Remnants" , "Bits and pieces, or slang fights" , "Slangy fights for leftovers" , "Throws away" , "Pieces of uneaten food" .)
