None merits exotic soup (10)
I believe the answer is:
minestrone
'soup' is the definition.
(minestrone is a kind of soup)
'none merits exotic' is the wordplay.
'exotic' is an anagram indicator.
'none'+'merits'='nonemerits'
'nonemerits' anagrammed gives 'MINESTRONE'.
(Other definitions for minestrone that I've seen before include "F" , "Item on menu" , "Italian soup" , "A starter" , "Dish" .)
