The burger was first introduced last year as a Bacon Portabella Melt with an upgraded bun.
Inside the brioche bun, you'll find a quarter-pound beef patty, sauteed portabella mushrooms, a slice of American cheese, thick-cut applewood-smoked bacon, and a warm cheddar cheese sauce.
The suggested price for Wendy's Bacon Portabella Melt on Brioche is $4.99. The burger is available through mid-December.
