Angus burger

Pre-made frozen Angus burgers are increasingly available from retailers.

Since 2006, McDonald's has test-marketed its own version of the sandwich in several markets, including Chicago, Illinois and upstate New York.

The test sandwich was offered in three varieties that had similar makeup of the standard Burger King version, the mushroom Swiss and the bacon cheese.

In mid-2009, two varieties of the Angus burger were added to McDonald's Australia and New Zealand menus.

The second is the "Mighty Angus", which consists of Angus beef, processed cheese, McChicken sauce, onion relish, red onion and bacon.
