The Flying Dutchman at In-N-Out(1 of 10)

This menu hack is seriously meat-tastic. Order the Flying Dutchman and you'll get two slices of American cheese sandwiches between two beef patties.

There's no bun or toppings, so it's an option for those going gluten free. Ask for it Animal Style if you want In-N-Out's special sauce smothered on top.
