Vegetable dish (11)
I believe the answer is:
ratatouille
'vegetable dish' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ratatouille that I've seen before include "Film" , "Stewed vegetable dish" , "cooked vegetables in a dish" , "Vegetable stew" , "vegetable casserole" .)
