Part of a Chinese meal, perhaps, one sold out (7)
I believe the answer is:
noodles
'part of a chinese meal perhaps' is the definition.
I can't judge whether this definition defines the answer.
'one sold out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'one'+'sold'='onesold'
'onesold' with letters rearranged gives 'NOODLES'.
Can you help me to learn more?
(Other definitions for noodles that I've seen before include "Narrow strips of pasta, or slang heads" , "Pasta ribbons" , "Far Eastern food" , "On instrument casually plays" , "Oriental pasta" .)
