No good getting upset over church in central Italy initially providing Italian cuisine (7)
I believe the answer is:
gnocchi
'italian cuisine' is the definition.
(Italian food)
'no good getting upset over church in central' is the wordplay.
'good' becomes 'g' (abbreviation).
'getting upset' indicates an anagram.
'over' says to put letters next to each other.
'church in' becomes 'chi' (I can't explain this - if you can you should give a lot more credence to this answer).
'central' becomes 'c' (common abbreviation in various government acronyms).
'no'+'g'='nog'
'nog' is an anagram of 'gno'.
'chi' put after 'c' is 'cchi'.
'gno'+'cchi'='GNOCCHI'
'italy initially providing' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Other definitions for gnocchi that I've seen before include "Dumpling dish" , "Italian dumpling made of potato, flour or semolina" , "Flour, semolina or potato dumplings" , "that is eaten" , "simple meal?" .)
