Wait to eat a Malaysian dish (5)
I believe the answer is:
satay
'malaysian dish' is the definition.
(I've seen this before)
'wait to eat a' is the wordplay.
'wait' becomes 'stay' (I've seen this before).
'to eat' means one lot of letters goes inside another.
'stay' enclosing 'a' is 'SATAY'.
(Other definitions for satay that I've seen before include "Spicy Malaysian sauce" , "spicy dish" , "Indonesian dish, skewered meat and sauce" , "something to eat" , "spicy sort of meat" .)
