So, it may come as a disappointment to the royal that one ingredient is well off the menu during royal tour.
According to The Sunday Express, Meghan - and the rest of the royal family - aren't allowed to eat garlic when they're on an official visit.
The paper reports: "Garlic is banned from being included in foods eaten by royal family members. With many meetings between official visitors, it is thought to be advised against to prevent any awkward bad breath."
Luckily for the royals, The Queen hates garlic so will never include it on any menus she curates.
"We can never serve anything with garlic or too much onions," Darren McGrady, royal chef at Buckingham Palace, explained to RecipesPlus. "The Queen would never have garlic on the menu."
It is already well-known that royals aren't allowed to dine on shellfish when they're travelling for royal visits, in case they're struck down with food poisoning.
She may have just joined the royal family and have the world's finest restaurants and chefs at her disposal but Meghan Markle's favourite meal is surprisingly low-key.
has just revealed what Prince Harry's wife's go-to dinner is and it proves she's a gal after our own hearts.
Rather than nibbling on a salad or indulging on some foie gras, Meghan prefers to chow down on poutine, which is essentially a vegan version of chips and gravy. God love her.
Meghan is apparently a huge fan of new vegan restaurant, By Chloe, which is situated in Covent Garden, and offers a vegan take on the dish.
By Chloe’s vegan version consists of chips, seitan 'chorizo', cashew nut cheese and vegan gravy. Delish.

When she's not indulging on chips and gravy, the royal-to-be kickstarts her day with a healthy and wholesome breakfast, which she credits for giving her that enviable, youthful glow.
Speaking about her approach to ageing and wellness, Meghan recently said: “As I’m getting older, my approach to ageing is quite different [..] I take care of my skin and body.
"And I don’t just take care of myself for aesthetic reasons, but because how I feel is dictated by what I’m eating, how much rest I’m getting and how much water I’m drinking.”
Meghan’s usual breakfast choice? Steel-cut oats with bananas or fruit topped with manuka honey and bee pollen.
