Garlicky shrimp dish (6)
I believe the answer is:
scampi
'garlicky shrimp dish' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scampi that I've seen before include "Large prawns as food" , "Dish of cooked shrimps or prawns" , "Prawns (fried with breadcrumbs)" , "Prawns, usually fried" , "Prawn dish" .)
