Bill bloater (4)
I believe the answer is:
pork
'bill bloater' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pork that I've seen before include "Meat used in sausages" , "Bacon, e.g." , "Meat used in chorizo" , "Cassoulet ingredient" , "Pig's flesh as food" .)
