Discard fresh, edible sandwiches (4)
I believe the answer is:
shed
'discard' is the definition.
(I've seen this before)
'fresh edible sandwiches' is the wordplay.
'sandwiches' indicates the answer is hidden within the clue (the answer is sandwiched in by the clue).
'SHED' is hidden within 'fresh edible'.
(Other definitions for shed that I've seen before include "Discarded" , "Remove clothes in small hut" , "Drop - cast off" , "Cast, wooden building" , "lost" .)
