The sandwich has been offered before but sometimes offers a few tweaks between appearances. This year sees a long bun sandwiching a spicy, crispy-fried chicken thigh, a German sausage patty, Emmental (Swiss) cheese, sauerkraut, and dill mustard.
A previous version had a hamburger bun, a crispy lemon chicken thigh, and sliced German chicken sausage.
Also being offered for a limited time along with the sandwich are battered potato wedges, BBQ McWings (i.e. Mighty Wings), and a Black Currant McFloat.
If you're wondering why it's not a Team Hong Kong or Team China-themed sandwich for the World Cup, it's because Hong Kong has never qualified and China has only done slightly better by qualifying once.
