Pass gun and dish (9)
I believe the answer is:
colcannon
'dish' is the definition.
(I've seen this before)
'pass gun' is the wordplay.
'pass' becomes 'col' (col is a term for a mountain pass).
'gun' becomes 'cannon' (cannon is a kind of gun).
'col'+'cannon'='COLCANNON'
'and' acts as a link.
(Other definitions for colcannon that I've seen before include "Vegetarian dish for 19 [PADRAIC]" , "Food for Irish" , "Irish cabbage, potato dish" , "plate for Seamus?" , "Traditional Irish dish of mashed potatoes and cabbage" .)
