It is one of the world's most popular dishes of all time with restaurants across the globe offering their own take on it, but now a California diner has claimed that the famous cheeseburger was in fact invented by mistake.

According to city officials, the cheeseburger's humble beginnings started when a young chef named Lionel Sternberger, working at 'The Rite Spot' accidentally burned one side of the hamburger he was cooking in the late 1920s.

Rather than throwing it away, fast-thinking Sternberger flipped it over, put a bit of cheese on it to disguise his mistake and served it to a customer. From that moment on the cheeseburger was born.

The town is now staking its claim as the birthplace of on the world tastiest inventions by launching a week of events in its honour.

Pasadena Cheeseburger Week, is set to promote restaurants in the area with a range of burger themed events.

The Pasadena Chamber of Commerce's Paul Little told "Most of these burgers are things people have eaten before. They perhaps just haven't thought of piling them on top of one another."
