A lot of food not originally from China? (4)
I believe the answer is:
east
'china?' is the definition.
(China is part of the East)
'a lot of food not originally' is the wordplay.
'a lot of food' becomes 'feast' (a large meal).
'not originally' means to remove the first letter (the origin of the word is removed).
'feast' with its initial letter taken off is 'EAST'.
'from' is the link.
(Other definitions for east that I've seen before include "Bridge player" , "4 dn 17 dn" , "Bidder after North (bridge)" , "Asia" , "Compass point at 90 degrees" .)
