4 KudoZ points awarded for this answer. Comment: "Thanks for your help. I'd put the question to my Brazilian ESL students this morning, and they came up with a variety of answers. One said cheiro verde can be used to refer to any green seasoning element, which seemed to be in line with my experience (at the supermarket, my roommate always says to go pick up cheiro verde, and when I return with with cebolinha he's satisfied). But a level-headed woman offered the same answer you've just given, so I'll accept that. Email me, though, if cheiro verde can include other green herbs like cuentro."
