First things first, slice your bagel in half and slather a thin layer of mustard on the bottom half. We're not messin' around here...

Now for the star: pile that sliced beef brisket high on the bottom bagel half. Don't be shy – it’ll be worth it. 

Next up, those essential sliced pickled gherkins. You want a good crunch with every bite.

Next up, a nice, thick dollop of that mustard, right over the gherkins. This is where the magic happens.

Lay those two glorious slices of Swiss cheese right on top. Nice and neat, covering all that meaty, tangy goodness.

Carefully place the top bagel half on your masterpiece. Now, grab hold and devour it like you mean it. This is what New York tastes like!
