Rush second spicy dish (6)
I believe the answer is:
scurry
'rush' is the definition.
(scurry is a kind of rush)
'second spicy dish' is the wordplay.
'second' becomes 's' (common abbreviation).
'spicy dish' becomes 'curry' (I've seen this before).
's'+'curry'='SCURRY'
(Other definitions for scurry that I've seen before include "Dash (like a mouse?)" , "Move hurriedly" , "Scamper" , "Move quickly" , "Scuttle" .)
