Dash, heading off for meal (5)
I believe the answer is:
curry
'meal' is the definition.
'dash heading off' is the wordplay.
'dash' becomes 'scurry' (I've seen this before).
'heading off' means to remove the first letter.
'scurry' with its initial letter taken off is 'CURRY'.
'for' acts as a link.
(Other definitions for curry that I've seen before include "groom" , "Vindaloo, for example" , "Hot spicy dish" , "Dress leather" , "Scratch" .)
