National Grilled Cheese Day

What do we know about the grilled cheese sandwich?

Creative cooks (and chefs) have been finding ways to melt cheese between (or on top of ) bread for years. The best search for the origin of the grilled cheese goes back to the 1920s and the Great Depression, thanks to the inexpensive bread and cheese readily available. The French claim their version, "The Croque Monsieur", is the original and it has been traced back to the early 1900s. A Croque Monsieur is an open faced sandwich with ham and cheese, often Gruyere. Thus, the debate at hand. Who was first to the grilled cheese game and is a Croque Monsieur technically a grilled cheese sandwich? Either way, I would like to simply say "thank you". Your invention has made my life (and millions of other lives) infinitely better. Who doesn't love a grilled cheese, toasted sandwich or cheese toastie?
