Ever since Pizza Hut stuffed cheese in a pizza crust, people have been coming up with more and more creative ways to make unhealthy food even less healthy by stuffing. This burger takes that to a whole other level.
A restaurant called Mister Eaters in Preston, England is now serving a hamburger where one of the patties has another ENTIRE CHEESEBURGER stuffed inside it.
They take a regular cheeseburger with the bun, surround it with more burger meat, then grill the whole thing.
Then they stack that monstrosity plus two more regular burger patties on four buns, with cheese, lettuce, and tomato.
It comes to at least 10,000 calories, and they're selling it for $33, although it's free if you finish it. (Metro)
