Chips and an odd green vegetable (7)
I believe the answer is:
spinach
'green vegetable' is the definition.
(I've seen this before)
'chips and an odd' is the wordplay.
'and' is a charade indicator (letters next to each other).
'odd' indicates anagramming the letters.
'chips' put after 'an' is 'anchips'.
'anchips' is an anagram of 'SPINACH'.
(Other definitions for spinach that I've seen before include "Some greens" , "Blackboard stand" , "food" , "Vegetable leaves" , "Popeye's strength-giver" .)
