A new food hack has revealed how to get a McDonald's Big Mac for almost half the price.

The trick published on #Hackthemenu shows how to build a bespoke meal from the chain’s secret menu that has the same taste as the iconic burger.

According to the site, a “Poor Man’s Big Mac” can be made by ordering a double cheeseburger without ketchup or mustard.

Then shredded lettuce and Big Mac sauce should be requested to give you the same taste as the Big Mac.

The middle bun found in the signature burger will be missing however the trick can save you £1.20 on your order.

It’s also healthier than the standard 550 calorie version with less cheese and bread.

The tip has now gone viral with hundreds of fast food fans sharing their favourite hacks on Facebook.

One user said: “I’ve been doing this for years, I used to get a bacon cheeseburger with Mac sauce but now I have to get a McDouble since they took it off the VP menu.”

Another offered a different solution to the hack: “Or you can order a Daily Double with Big Mac sauce instead of mayo (comes with lettuce, pickle and onion but no mustard or ketchup).”

One user wrote: “I've always wondered why McDonald's didn't come out with the 'Little Mac' with just a single burger, no 3 buns, but the sauce and lettuce. I once tried to contact to company to suggest it, but their website says they don't take suggestions.

"Well, it's OK, since now with the new 'secret menu', which basically means you can put any of their products on a bun, it's all good.”
