Narrow stripe in piece of meat round end of skewer (6)
I believe the answer is:
streak
'narrow stripe' is the definition.
(streak can mean a stripe or strip)
'piece of meat round end of skewer' is the wordplay.
'piece of meat' becomes 'steak' (steak is a type of meat).
'round' means one lot of letters goes inside another.
'end of' says to take the final letters.
The final letter of 'skewer' is 'r'.
'steak' enclosing 'r' is 'STREAK'.
'in' acts as a link.
(Other definitions for streak that I've seen before include "Band of colour - run naked" , "Unbroken series of events" , "Run unclothed" , "Run naughtily nude in public" , "run out of gear" .)
