(Undated) -- Fire up the grill today or hop on over to your favorite burger joint because National Cheeseburger Day.
The cheeseburger was invented in the 1920s.
The savory sandwich is made by placing a slice of American, cheddar, swiss or other kind of cheese onto a patty while it's still cooking to ensure that it's properly melted.
Then you can add some lettuce, tomato, bacon and other toppings, plus a condiment or two.
When it's all ready to eat, be sure to enjoy it with some French fries.
