Happy National Grilled Cheese Sandwich Day!

National Grilled Cheese Sandwich Day is celebrated annually on April 12. Since it's one of the most popular comfort foods in the world, it should be celebrated daily.

According to the National Day Calendar, bread and cheese have always been commonly paired to eat together. But it was not until the '20s when toasted bread and melted cheese became a prominent snack food. In fact, it originally was consumed without two slices of bread.

So, to enhance your grilled cheese sandwich game, be sure to try new cheese and bread combinations. Even more, don't be afraid to experiment with different sauces and toppings. The best part is, you can be as creative as you want.

Obviously, the best way to celebrate this day is to make yourself, your friends and your family the delicious treat. So be sure to publish cheesy posts on social media using #GrilledCheeseSandwichDay today!

Here are 10 different versions of this sandwich that will make your jaw drop and eyes widen.
