As we reported a few months back, McDonald’s will be rolling out a new breed of deliciousness under the alias of the Angus Third Pounder. This is McDonald’s first new burger offering since the Big ‘N Tasty debuted back in 2001. These new burgers come in the form of the Deluxe, Bacon & Cheese and Mushroom & Swiss, each made with a third-pound of 100-percent Angus beef and served on a toasted bakery-style sesame seed roll.
