The royal wedding day is fast approaching. On Saturday, after months of anticipation, Prince Harry and Meghan Markle will marry in St George’s Chapel at Windsor Castle.

We already know quite a few details about the day: who will perform, who won’t attend, and how the “inner circle” will celebrate after.

We don’t know exactly what the newlywed royal couple will serve to their guests — but former royal chef Darren McGrady told Travel + Leisure what to expect. In honor of the day, McGrady hosted a royal wedding breakfast in partnership with Kellogg's, featuring some of the family's favorite cereals (the Queen eats Special K every morning).

After the ceremony, 600 guests will attend a standing reception with passed appetizers and bowls, perhaps something like poke. McGrady said that this will be “a great chance for Meghan to pass around her quinoa” and show off her preference for healthy eating. But Harry may choose to highlight the food of his country with this menu.

“Harry loves all the nursery foods,” McGrady said, “the traditional British foods and the things like shepherd’s pie.” Particularly those that use lamb from Highgrove Estate (owned by Prince Philip).

Royal chefs refused to reveal exactly what will appear on this weekend’s menu, but McGrady said that their job is to try to showcase local cuisine from England. “We always tried to do it seasonally,” McGrady said. “We also tried to include dishes from the royal estates, whether it’s venison from Sandringham or growl from Von Moral, or the peaches from Windsor.”

The head chef of the royal household revealed that some of the produce on the menu was taken directly from Her Majesty the Queen's Estate at Windsor.

When it comes time to cut the cake, Meghan has chosen to serve a “sponge cake with elderflower and lemon and cream cheese frosting,” McGrady said. But perhaps there will be a secret treat for Harry somewhere on the dessert table as well. According to the chef, Harry’s favorite dessert is caramel banana cake.

A separate dinner — catered by an outside company and paid for by Prince Charles — will be held at Frogmore Estate in the evening.
