Mexican dish and a Chile stew (9)
I believe the answer is:
enchilada
'mexican dish' is the definition.
(enchilada is a type of Mexican dish)
'and a chile stew' is the wordplay.
'stew' indicates anagramming the letters.
'and'+'a'+'chile'='andachile'
'andachile' anagrammed gives 'ENCHILADA'.
(Other definitions for enchilada that I've seen before include "Mexican dish" , "Filled tortilla served with chilli sauce" , "spicy dish" , "Mexican food" , "Mexican tortilla with chilli" .)
