How do you hinge cut the bread at subway?

To hinge cut a sub at Subway, first, place the sandwich on a clean cutting board. Using a sharp knife, make a cut along the top of the bread, not cutting all the way through, but enough to create a hinge. This allows the sandwich to open like a book, making it easy to add toppings and sauces without spilling. Finally, customize your sandwich with your desired ingredients.
