New York City’s Chopped Cheese Sandwich with chopped beef burgers, melted gooey cheese, caramelized onions, topped with tomatoes and shredded lettuces, and hugged by a toasted hero roll. This is the classic way to make the iconic NYC chopped cheese. It reminds me of Philly cheesesteak, but even better!
Slice hero rolls 3/4 of the way through with a serrated knife.
Add oil to a large non-stick skillet over medium high heat. Add diced onions and sauté until caramelized. Transfer to a bowl and set it aside.
Spread a thin layer of mayo on the hero roll. Drizzle ketchup on top.
