EU makes speeches about the end of irregular vegetables (8,7)
I believe the answer is:
brussels sprouts
'vegetables' is the definition.
(brussels sprout is a kind of vegetable)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for brussels sprouts that I've seen before include "Vegetables" , "part of the traditional 27 [DINNER] - with 8a" , "greens" .)
