Use this information how you see fit. If you take a Burger King Double Stacker and pull the patties apart, they fit perfectly on top of a Burger King Long Chicken sandwich. Pictured above, there's a Double Stacker on top of a Mexican Chicken Sandwich. It's a sodium bomb, which left me feeling swollen and sluggish. For the remainder of the day, I smelled greasy. Between the cheese and spice of the Mexican Chicken, and the savory bacon of the Double Stacker, the flavors were...uh...interesting. I wonder if there would be a way to modify the Chicken Sandwich to make it work better with the Double Stacker sandwich. The overall experience was something that would've been cool when I was 17 or 18, but...man, eating this at 35 was a poor decision.
