Kevin shortly consuming one chicken dish (4)
I believe the answer is:
kiev
'chicken dish' is the definition.
(I've seen this in another clue)
'kevin shortly consuming one' is the wordplay.
'kevin shortly' becomes 'kev' (I can't explain this - if you can you should believe this answer much more).
'consuming' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'kev' going around 'i' is 'KIEV'.
Can you help me to learn more?
(Other definitions for kiev that I've seen before include "FC Dynamo/chicken ___" , "Ukrainian capital" , "Ukraine's largest city" , "Ukraine's capital - way of cooking chicken" , "Capital of 13 down" .)
