McDouble

The McDouble is a hamburger sold by the fast-food restaurant chain McDonald's. It is a variation on the double cheeseburger, with only one slice of cheese placed between the two beef patties. It was introduced in 1997. It is one of the cheapest products sold by the company, and for this reason is often included in the chain's budget menus.

Description
The burger contains 390 calories, 23g of protein, 7% of daily fiber and 20% of daily calcium. It is the cheapest way to buy a burger similar to the Big Mac, and was also referred to as a lifehack, as the burger is half the price of a Big Mac, while still containing the same amount of beef as the Big Mac

History
The McDouble was introduced in 1997, garnished with lettuce, tomatoes, and mayonnaise instead of the cheese that currently tops it.

The Bacon McDouble was introduced and cost $2. This sandwich was also added to the U.S. "Dollar Menu & More" in November 2013.

The Daily Double, similar to the McDouble but with slightly different toppings, was test marketed in 2011 and 2012.

People on social media, including some radio announcers, claimed that the McDouble was the cheapest and most nutritious food,  and it was also claimed to be the cheapest alternative to junk foods. In 2024 the sandwich became a popular meme in blockchain communities as $mcdubble.
