Fire up the grill or head to your favorite restaurant because today is National Cheeseburger Day! 

There are several theories about the origins of the cheeseburger. One story claims that the cheeseburger was created between 1924 and 1926 by a chef named Lionel Sternberger. As the story goes, a homeless man dining at Sternberger's restaurant in Pasadena, California, suggested the addition of a slice of cheese to his hamburger order. Sternberger complied, eventually added it to his menu, and the rest is history. 

Since then, cheeseburgers have become a staple at American cookouts and restaurants. Hungry yet? We hope you enjoy National Cheeseburger Day today!
