American chose fresh European pasta dish (8,6)
I believe the answer is:
macaroni cheese
'pasta dish' is the definition.
(I know that macaroni cheese is a type of pasta dish)
'american chose fresh european' is the wordplay.
'fresh' indicates anagramming the letters (a fresh re-ordering of the letters).
'european' becomes 'E' (abbreviation e.g. EU).
'american'+'chose'='americanchose'
'americanchose' is an anagram of 'macaronichees'.
'macaronichees'+'e'='MACARONI CHEESE'
(Other definitions for macaroni cheese that I've seen before include "melted in dish" , "Instead of this savoury" , "Savoury pasta dish" , "dish - with 29a" , "food" .)
