Can’t join Prince William and Kate at the Foundation Polo Challenge in California on Saturday?

Then try this dish – one that Giada De Laurentiis will be preparing for the royal couple at the event – at home instead.

“It’s elegant comfort food,” the celebrity chef tells PEOPLE of her recipe.

Polo-viewing optional.
