Fast food restaurants regularly bring in new items to jazz up the menu and keep people coming through the doors.
Some of them become fan favourites and end up being permanent fixtures and others are roasted on social media and are quickly deleted.
It seems as though the McDonald's Veggie Burger has had success in some places and been dumped by the public in others. In Australia, it's certainly been a mixed reaction.
Some people were quick to criticise it while others seemed pretty stoked. One person wrote: "I'm gonna deep throat the fuck out that McVeggie."
When Singapore introduced the meat free burger, Aussies were begging for it to be brought to our shores and when it was it wasn't met with the same type of excitement.
A spokesperson told news.com.au in 2016: "We have had a vegetarian burger on the menu before but unfortunately they don't stay on the menu when demand falls away."
But it looks as though the Big M is giving it another crack by trialling the McVeggie in South Australia. You'd think it being three years later and a lot more health conscious people out there that it'd be a hit, right?
After the trial is complete in South Australia, Macca's bosses will have a look at the feedback and see whether they should roll it out across the country.
The patty is made from a blend of potato, peas, corn, carrot, onion and will be topped with the regular McDonald's stuff like cheese, lettuce, mayonnaise and pickles or gherkins.
Jo Feeney, marketing director at McDonald's Australia, said: "We understand there's a rising demand for vegetarian options, and we always look to give our customers more of what they want.
"We're excited to be trialling the McVeggie burger in South Australia so our customers can give us feedback on it before we look to serve it up across the country."
If you want to know how to get some of the more secretive items on the McDonald's menu listen to this former manager.
The unidentified Glasgow store manager said: "You can order from the 'Secret Menu'. Just like with any of our sandwiches, you can add, remove or change ingredients by special request. These are called 'grill orders' (i.e. Big Mac no pickle).
"Order one and the workers might not know it by name (i.e. Land, Air and Sea burger or the McGangBang) but if you explain what it is, and are willing to pay for all the ingredients, it's just another 'grill order' that we can make up."
