Chips with an odd vegetable (7)
I believe the answer is:
spinach
'vegetable' is the definition.
(spinach is a kind of vegetable)
'chips with an odd' is the wordplay.
'with' is a charade indicator (letters next to each other).
'odd' indicates anagramming the letters.
'chips'+'an'='chipsan'
'chipsan' anagrammed gives 'SPINACH'.
(Other definitions for spinach that I've seen before include "Leafy vegetable" , "Popeye's strength-giver" , "Some greens" , "food" , "Vegetable plant" .)
