Emptied bin filled with uncooked meat (5)
I believe the answer is:
brawn
'meat' is the definition.
(I've seen this before)
'emptied bin filled with uncooked' is the wordplay.
'emptied' suggests removing the centre.
'filled with' indicates putting letters inside.
'uncooked' becomes 'raw' (similar in meaning).
'bin' with its middle removed is 'bn'.
'bn' enclosing 'raw' is 'BRAWN'.
(Other definitions for brawn that I've seen before include "perhaps, a sandwich filling" , "Physical strength; cooked meat" , "Muscle; strength" , "Jellied meat - muscle" , "Pressed cooked meat; strength" .)
