Harry and Meghan are expecting their first child together in late April or early May.
At which point, Meghan went off script after something she was reminded of a way to make the packed lunches even more meaningful. Instead of writing the notes on paper, she made a decision to write them on bananas.
A royal correspondent, Hannah Furness tweeted that Meghan saw the food and came up with the idea to write some strong and empowering messages on the bananas.
While helping volunteers put together care packages with food, Meghan took inspiration from a school cafeteria worker in the USA who wrote motivational messages to children. But the Duke and Duchess of Sussex have continued their quest to spotlight causes that others might not be willing to address.
"Do you have a Sharpie marker?"
As well as visiting the Old Vic Meghan and Harry visited met volunteers and helped out in the One25 charity kitchen.
Printing messages like "you are fearless", "you are strong", "you are loved", and "you are special" on the bananas, the Duchess surprised One25's kitchen volunteers with her spur-of-the-moment plan.
The former "Suits" actress wrote kind messages on bananas for some of the women One25 helps, penning notes like "You are special!" The expert also said that Markle will seek the support of some of her friends who are in London because she doesn't want to be completely reliant on her husband.
"Little things like that when you are out - especially tonight if there's women out there, we can see the weather - just to get that little thing".
New York Times writer Caity Weaver deemed the gesture "kind" while twitter user Frances07834377 said: "Sometimes a little thing you do gives happiness to someone".
