Cook scans food to welcome Italy's top police officer (5,9)
I believe the answer is:
chief constable
'police officer' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for chief constable that I've seen before include "Bobby's superior" , "Busy high up" , "Police officer" , "law enforcer" .)
