Flatten vegetable (6)

I believe the answer is:

squash

This clue is a double definition.

'flatten' is the first definition.
(I've seen this before)

'vegetable' is the second definition.
(squash is a kind of vegetable)

(Other definitions for squash that I've seen before include "Flatten" , "Fruit - drink - crush" , "Racket game or vegetable gourd" , "Crush; gourd" , "Drink; gourd" .)

I've seen this clue in the Sydney Morning Herald.
