World's Tastiest Sandwiches 

But regardless of how the ubiquitous sandwiches on this list came to be, 

there is one thing that is true for each and every one of them: they are incredibly tasty, they are one of a kind, and they are worth looking for. 

When compared to the origins of many other sandwiches, the cheesesteak, which is a staple in Philadelphia, 

has a history that is well documented and generally uncontested.

Pat Olivieri, who ran a hot dog stand, is credited with inventing the sandwich during the year 1930.  

He did so by placing some shaved beef on the grill in order to make a sandwich.  

Pat changed the name of his hot dog shop to Pat's King of Steaks after a cab driver noticed the delectable dish and asked for one.
