Prawns (6)
I believe the answer is:
scampi
'prawns' is the definition.
(I have seen 'Large prawns' mean 'scampi' so perhaps 'prawns' could also mean 'scampi')
This is all the clue.
(Other definitions for scampi that I've seen before include "Norway lobsters -- Dublin Bay prawns" , "Cooked Norway lobster" , "Crumbed prawns" , "Dish of fried shrimps or prawns" , "Prawns (fried with breadcrumbs)" .)
