French word for "soup vegetables"?

I was wondering: what is the French equivalent of "soup vegetables"? It isn't "soupe de l�gume". That would be plainly "vegetable soup". That's not what I mean. I have a recipe that calls for soup vegetables (e.g. carrots, celery, leeks, and parsley). So, what would "soup vegetables" be called in French?! This is sort of urgent. Thanks in advance!
