Hunk of meat (4)
I believe the answer is:
slab
'hunk of meat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for slab that I've seen before include "Thin flat stone" , "Piece, e.g. of cake" , "Hunk" , "Flat piece of stone or 20" , "Large block of stone or concrete" .)
