FROM triangles to quarters or simply cut in half, we all have preferences on how our sandwiches are made.
She may be a Princess, but Kate Middleton is just like the rest of us when it comes to having rather particular food preferences and aversions.
That's because former royal chef Graham Newbould revealed the Princess of Wales reportedly always steers clear of square-shaped sandwiches.
But rather interestingly, it's not just the mum-of-three who follows the unusual quirky habit, it's all royals.
Why? Well, it's all because of a superstition that's been passed down several generations.

Many royal family members are thought to have the same food aversion as it's linked to the belief that the person who serves the food could be attempting to damage the monarchy.
In the documentary Secrets of the Royal Kitchen, Graham revealed: "The royals never have square sandwiches because tradition has it that anyone presenting them with pointed-edged food is trying to overthrow the throne of England."
The former royal chef, who worked at Buckingham Palace for two years and six years at Kensington Palace, also claimed that while working for the late Queen Elizabeth he never once prepared square sandwiches for her.
Instead, she reportedly tucked into “jam penny” sandwiches as part of her afternoon tea.
It's also thought that Queen Victoria's husband, Prince Albert, followed the same superstitious beliefs because he allegedly thought that eating coffin-shaped food was deemed unlucky.

And it's not the only food aversion that Kate Middleton follows either, as Fabulous previously told how she's banned from enjoying a particular type of food whilst travelling.
The late Queen Elizabeth implemented a strict set of rules for all royals to follow when they're abroad - with eating shellfish at the top of the list due to its fairly high risk of food poisoning.
British etiquette expert Grant Harrold told Woman & Home magazine: "It's a very sensible move to abandon having seafood when out and about on public duties.

MAAM'S RULES
Not only this, but carbs are banned too, as the late Queen was allegedly not a fan of pasta or potatoes.
Foie Gras is also apparently forbidden as in 2008 the then-Prince Charles set the ban due to animal welfare worries.
The now-king is also believed to be rather fussy when it comes to his breakfast.

"He normally starts the day with some fruit for breakfast, often some plums from the garden that have been lightly poached," said former royal chef Darren McGrady, speaking to Delish.
A little juice and some muesli to go with it."
Meanwhile, Royal Chef Graham Newbould also revealed: "Wherever the Prince goes in the world, the breakfast box goes with him.
"He has six different types of honey, some special mueslis, his dried fruit and anything that's a bit special that he is a bit fussy about."
