Easy to cook since it's all up in your grill! The grilled cheese sandwich is one of the most popular sandwiches of all time. It's both easy and affordable. Kids love them, college students live off of them, and chefs obsess over gourmet versions of them. But how much do we know about the cheesy goodness we are putting in our mouths? Here are some fun facts about the grilled cheese:

1. Originally, the grilled cheese did not start out as a sandwich but rather a slice of cheese on a slice of bread. It was not until the 1960s that the second piece of bread was added, truly making it a sandwich.

2. Before its aforementioned debut, the grilled cheese was known as "melted cheese," "toasted cheese," or "cheese dream."

3. It is the fourth most popular sandwich in the USA behind ham, turkey, and peanut butter & jelly.

4. Approximately 3/4 of people who buy sliced cheese make at least one grilled cheese sandwich per month.

5. Americans consume more than two billion grilled cheese sandwiches a year, about 8.4 a person.

6. The typical grilled cheese sandwich contains about 291 calories. If you are looking to try a healthier version use whole wheat bread, margarine, and low fat cheese as substitutes.

7. The Guinness world record for eating grilled cheese was set in 2006. Competitive eater, Joey Chestnut, ate 47 sandwiches in 10 minutes.

8. April is recognized as National Grilled Cheese Month.

Just how affordable is a grilled cheese? There are gourmet chefs that price theirs starting at hundreds of dollars or more a sandwich because they are adorned with 24 karat edible gold or finely aged cheese. Exemplifying such standards is the restaurant, Serendipity 3, who sells the sandwich formally named "The Quintessential Grilled Cheese Sandwich" which is sold for 214 dollars; it holds the Guinness world record for the most expensive sandwich commercially available. However, an affordable alternative can be found just around the corner at your local fast food chains like McDonald's and Wendy's by simply asking for a cheeseburger without the meat. So the next time you are hungry and looking for something fast to make—or inexpensive to order—there is no going wrong with choosing a grilled cheese sandwich. Enjoy!
