In Austria, Hungary and Germany you can eat Goulash already a long time ago. There are a lot of different types of Goulash. The origin is in Hungary, but now you can eat it in different countries.I'm not a pro, but I'd like to show you a easy receipt.
Normally you can put almost everything in a Goulash. Maybe it's close to stew? I found all ingredients in Japan too so please try it out ;)
