I found this information on Wikipedia. Lots of information. Print this off and take it to your butcher. He should be able to give you what you need with this information. http://en.wikipedia.org/wiki/Hanger_steak
Hanger/Skirt steak is used for fajitas, never had it out of the US, Mexico, or other Latin American country, but you could also use London Broil cut or other steak for this recipe. Recommend asking your butcher what cuts are available in your countries. Good luck.

I live in Canada--what is Hanger steak or skirt steak. I have never heard or it before
