One's abrupt shredding a vegetable for the chow mein? (4,6)
I believe the answer is:
bean sprout
'a vegetable for the chow mein?' is the definition.
'one's abrupt shredding' is the wordplay.
'shredding' indicates anagramming the letters.
'ones'+'abrupt'='onesabrupt'
'onesabrupt' anagrammed gives 'BEAN SPROUT'.
(Other definitions for bean sprout that I've seen before include "vegetable" , "One may be prepared for Chinese" .)
