Steal from Savoy? (7)
I believe the answer is:
cabbage
I believe this clue is a double definition.
'steal' is the first definition.
(I know that cabbage is a more specific form of steal)
'savoy?' is the second definition.
(savoy is a kind of cabbage)
'from' is the link.
(Other definitions for cabbage that I've seen before include "Savoy vegetable" , "A Brassica plant" , "Vegetable plant" , "Green vegetable" , "Variety of brassica" .)
