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' means one lot of letters go next to another.
'odd' is an anagram indicator.
'chips' put after 'an' is 'anchips'.
'anchips' anagrammed gives 'SPINACH'.
(Other definitions for spinach that I've seen before include "Leafy vegetable" , "Popeye's strength-giver" , "Some greens" , "food" , "Vegetable plant" .)
