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' means to remove the middle letters.
'filled with' is an insertion indicator.
'uncooked' becomes 'raw' (similar in meaning).
'bin' with its middle removed is 'bn'.
'bn' going around '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" .)
