Starts to regret eating stuffing coloured like a kebab? (8)
I believe the answer is:
skewered
'like a kebab?' is the definition.
(kebabs are often served on skewers)
'starts to regret eating stuffing coloured' is the wordplay.
'starts to' indicates taking the first letters.
'stuffing' is an insertion indicator.
'coloured' becomes 'skewed' (both can mean biased or distorted).
The first letters of 'regret eating' is 're'.
're' inserted inside 'skewed' is 'SKEWERED'.
(Other definitions for skewered that I've seen before include "Pierced with metal pin" , "Fastened together by a pin" , "Pierced through with meat pin" , "Transfixed" , "Run through" .)
