After church, working women will take in island food (4,4)
I believe the answer is:
chow mein
'food' is the definition.
(chow mein is a kind of food)
'after church working women will take in island' is the wordplay.
'after' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation).
'working' indicates an anagram.
'will take' is an insertion indicator.
'in island' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'women' with letters rearranged gives 'owmen'.
'owmen' placed around 'i' is 'owmein'.
'ch' put next to 'owmein' is 'CHOW-MEIN'.
Can you help me to learn more?
(Other definitions for chow mein that I've seen before include "Chinese dish of noodles, meat and veg" , "take-away food" , "'Chinese dish with fried noodles (4,4)'" , "Chinese noodle dish" , "Chinese/US noodle dish" .)
