Hamburger: Why This Food Does Not Contain Ham?

Another argument being raised about burgers is if it is a sandwich or not. To solve this, you must first know the origin of the sandwich. The Earl of Sandwich in the 18^th century became frustrated with the way mealtime was constantly interrupting his day.

So, he ordered his cook to serve a meat placed between two slices of bread so that he can still continue his duties while having his meal. With this, the sandwich was invented.
