Anyone who's had the eccentric pleasure of grabbing a bite from a Japanese convenience store will recognise this iconic sandwich! It’s been popping up on cafe menus all over Australia in recent years, often made with chicken, but in Japan it’s made with thick and juicy panko crumbed pork cutlets. Equally thick slabs of fluffy white bread are the key to authenticity here, paired with shredded cabbage, classic tonkatsu BBQ sauce and hot mustard.
