Hurries back with a companion, getting vegetable (7)
I believe the answer is:
spinach
'vegetable' is the definition.
(spinach is a kind of vegetable)
'hurries back with a companion' is the wordplay.
'hurries' becomes 'nips' (nip can mean to move quickly).
'back' says the letters should be written backwards.
'with' says to put letters next to each other.
'companion' becomes 'ch' (I've seen this in other clues).
'nips' written backwards gives 'spin'.
'spin'+'a'+'ch'='SPINACH'
'getting' acts as a link.
(Other definitions for spinach that I've seen before include "Leaf vegetable" , "Popeye's vegetable" , "Vegetable leaves" , "something to eat" , "Leafy vegetable" .)
