Vegan food fight's ending with saucer being thrown back (4)
I believe the answer is:
tofu
'vegan food' is the definition.
'tofu' can be an answer for 'food' (tofu is a kind of food). I'm not certain of the 'vegan' bit.
'fight's ending with saucer being thrown back' is the wordplay.
'ending' suggests the final letters (the letter at the end of the word).
'with' is a charade indicator (letters next to each other).
'saucer' becomes 'ufo'.
'being thrown back' says the letters should be written backwards.
The final letter of 'fight' is 't'.
'ufo' backwards is 'ofu'.
't'+'ofu'='TOFU'
Can you help me to learn more?
(Other definitions for tofu that I've seen before include "Substitute for meat" , "fare from Japan" , "Food made from beans" , "Cheese-like vegetarian food" , "Soy bean curd" .)
