Rice dish is too much in centre of Verona (7)
I believe the answer is:
risotto
'rice dish' is the definition.
(I've seen this before)
'is too much in centre of verona' is the wordplay.
'too much' becomes 'OTT' (short for over the top).
'in' indicates putting letters inside.
'centre of' indicates the central letters.
The middle of 'verona' is 'ro'.
'is'+'ott'='isott'
'isott' put into 'ro' is 'RISOTTO'.
(Other definitions for risotto that I've seen before include "Italian dish of rice, meat and vegetables" , "scoff" , "Italian course" , "food dish" , "It has roots in Italian rice-based dish" .)
