Garlicky dish (6)
I believe the answer is:
scampi
'garlicky 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 "Dish of fried shrimps or prawns" , "Tasty prawns in batter" , "Prawns, usually fried" , "Prawn dish" , "sort of seafood" .)
