Sandwich with brown bread from Ireland (7)
I believe the answer is:
toastie
'sandwich' is the definition.
(I have seen 'Toasted sandwich ' mean 'toastie' so perhaps 'sandwich' could also mean 'toastie')
'brown bread from ireland' is the wordplay.
'brown bread' becomes 'toast' (I've seen this in another clue).
'from' means one lot of letters go next to another.
'ireland' becomes 'ie' (two letter country code).
'toast'+'ie'='TOASTIE'
'with' is the link.
(Other definitions for toastie that I've seen before include "Browned sandwich" , "Hot sandwich" , "Warm snack" , "Hot snack (informal)" , "Grilled food" .)
