Internal organs as food (5)
I believe the answer is:
offal
'internal organs as food' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for offal that I've seen before include "Meat product" , "Worthless parts of animal carcass" , "Edible innards" , "Butcher's stock" , "Less valuable edible parts of animal" .)
