Vehicles stuffed with rubbish vegetables (7)
I believe the answer is:
carrots
'vegetables' is the definition.
(carrot is a kind of vegetable)
'vehicles stuffed with rubbish' is the wordplay.
'vehicles' becomes 'cars' (car is a kind of vehicle).
'stuffed with' means one lot of letters goes inside another (I've seen this in other clues).
'rubbish' becomes 'rot' (I've seen this before).
'cars' going around 'rot' is 'CARROTS'.
(Other definitions for carrots that I've seen before include "Enticing vegetables" , "Root vegetables" , "Edible orange roots" .)
