Fish European Parliament rejected as a food item (6)
I believe the answer is:
peanut
'item' is the definition.
(I have seen 'Item of fruit' mean 'peanut' so perhaps 'item' could also mean 'peanut')
'fish european parliament rejected as a food' is the wordplay.
I cannot quite see how this works, but
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found in the answer.
'a' could be 'an' and 'an' is found within the answer.
The remaining letters 'put' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for peanut that I've seen before include "Satay ingredient" , "Seed also known as a goober" , "Popular edible seed, often salted" , "Leguminous seed eaten as snack or butter" , "Bar nibble" .)
