Chopped lion meat (4)
I believe the answer is:
loin
'meat' is the definition.
(loin is a kind of meat)
'chopped lion' is the wordplay.
'chopped' indicates an anagram.
'lion' with letters rearranged gives 'LOIN'.
(Other definitions for loin that I've seen before include "Beef cut" , "Cut of meat from between the ribs and rump" , "Either side of the backbone between the hip bone and ribs" , "Meat between the ribs and rump of an animal" , "Part of the body to which "lumbar" refers" .)
