End of shocking scam over Greek character's dumplings (7)
I believe the answer is:
gnocchi
'dumplings' is the definition.
(I've seen this before)
'end of shocking scam over greek character's' is the wordplay.
'end of' says to take the final letters.
'scam' becomes 'con' (both can mean a fraudulent scheme).
'over' says the letters should be written backwards.
'greek character' becomes 'chi' (letter from the Greek alphabet).
The final letter of 'shocking' is 'g'.
'con' written backwards gives 'noc'.
'g'+'noc'+'chi'='GNOCCHI'
(Other definitions for gnocchi that I've seen before include "simple meal?" , "Small dumplings used like pasta" , "2 [PASTA]" , "Little dumplings" , "Flour, semolina or potato dumplings" .)
