Greek character wanting English dish (3)
I believe the answer is:
pie
'dish' is the definition.
(I've seen this before)
'greek character wanting english' is the wordplay.
'greek character' becomes 'pi' (letter from the Greek alphabet).
'wanting' means one lot of letters go next to another.
'english' becomes 'e' (abbreviation).
'pi'+'e'='PIE'
(Other definitions for pie that I've seen before include "Very easy answer as" , "Pasty - former Indian coin - mixed type - bird" , "steak might go in this" , "In the sky, it's an unrealistic prospect" , "Small, former Indian coin" .)
