Meal at work? Spooner’s had no impact (6,5)
I believe the answer is:
packed lunch
'meal at work?' is the definition.
(you might take a packed lunch to work)
'spooner's had no impact' is the wordplay.
I cannot really see how this works, but
'had' could be 'packed' (packing is a kind of having) and 'packed' is located in the answer.
'no' could be 'n' (common abbreviation y/n) and 'n' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for packed lunch that I've seen before include "Cold meal (eg, taken to school)" , "Ready-prepared midday meal in container" , "Food carried on a day trip" , "Meal to be carried" .)
