Half dying to tuck into green food? That's a landmark for Americans! (7,8)
I believe the answer is:
lincoln memorial
'landmark for americans' is the definition.
(memorial in Washington DC)
'half dying to tuck into green food? that's a' is the wordplay.
I cannot quite understand how this works, but
'into' could be 'in' and 'in' is found in the answer.
'food?' could be 'e' (E is an example) and 'e' is found in the answer.
'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for lincoln memorial that I've seen is " monument".)
