Marshmallow Fluff and Duke’s Mayonnaise Sandwich (our history) on Sandwiches of History⁣ I just want to say up front, thanks for watching Sandwiches of History. It’s been a lot of fun and hopefully after you unfollow me today, you’ll come back some day. That’s because today I am doing a sandwich of our history that really sounds terrible but turns out, isn’t. It was put out into the universe by Sad Beige Lady. It’s a sandwich she says her son’s favorite. And my mind is blown. #fyp #sandwichesofh
