I was reminded that McDonalds has various regional favorites around the world that can't be bought in the USA.
The Chicken Maharaja Mac
With India being a predominantly Hindu country, and cows being sacred in Hinduism, beef is not a commercially viable (and in many states, legal) option for a Big Mac. When McDonald's first opened up in India, the beef was replaced with lamb. But now the magic formula has been struck, and the patties are made of chicken. Gone too, however, are the pickles. In India's version, there are jalapenos, and the usual mustardy-mayonnaise "secret" sauce is replaced with a fierier habanero alternative.
. . .
The bifana is Portugal's national sandwich, and it's little more than pork in bread. Traditionally, this is stewed pork, but a lot of places use grilled pork instead. And McDonald's has joined the latter with its McBifana. In doing so, it has kept things very simple. It's two pork patties, shunted inside a hard, semi-crusty roll, and with a slightly sour sauce.
There are more examples at the link.
I wonder if McDonalds could be persuaded to bring some of those to its US customers? I'd like to try them.
