Feel vain? Cooked Greek food wrap? (4,4)
I believe the answer is:
vine leaf
'greek food wrap?' is the definition.
I know nothing about this answer so I can't tell whether this works.
'feel vain? cooked' is the wordplay.
'cooked' is an anagram indicator (letters cooked into a new form).
'feel'+'vain'='feelvain'
'feelvain' is an anagram of 'VINE-LEAF'.
Can you help me to learn more?
(Other definitions for vine leaf that I've seen before include "dolma" , "Wrapper used to make dolmades" .)
