Cabbage is OK with a chip salad (3,4)
I believe the answer is:
pak choi
'cabbage' is the definition.
(I have seen 'Chinese cabbage ' mean 'pak-choi' so perhaps 'cabbage' could also mean 'pak-choi')
'ok with a chip salad' is the wordplay.
'with' is a charade indicator (letters next to each other).
'salad' indicates an anagram (salad can refer to a mixture).
'a'+'chip'='achip'
'ok' after 'achip' is 'achipok'.
'achipok' anagrammed gives 'PAK-CHOI'.
'is' is the link.
(Other definitions for pak choi that I've seen before include "Leafy green Chinese vegetable" , "Chinese vegetable with white stalks and dark green leaves" , "Chinese cabbage" .)
