Film buff foodies will never forget the "Spanglish" sandwich. When Adam Sandler needed an "ultimate sandwich" for "Spanglish" (2004), the "World's Greatest Sandwich" made its Hollywood debut. It's technically just a BLT with egg and cheese, but Chef Thomas Keller created this iconic bite for the movie, and the 3-in-1 sandwich has taken on a life of its own since hitting the big screen. In the film, Adam Sandler plays a lauded professional chef - and in one scene, his character creates "The World's Greatest Sandwich." The film team approached Keller and asked the real-life chef to create his idea of the ultimate sandwich for the movie, and the 3-in-1 was born. Keller also served as a food consultant for another gastronomic film, Pixar's "Ratatouille" (2007).
