Sandwich Components

Method

Preparation and Assembly

  1. 1

    Caramelize the Onions

    Heat 2 tablespoons of olive oil in a skillet over medium heat. Slice the large onion thinly and add it to the skillet. Sprinkle with salt and pepper. Cook, stirring occasionally, for about 15-20 minutes until the onions are soft and caramelized.

  2. 2

    Prepare the Beef Roast

    Season the half pound of beef roast with salt and black pepper. You can either cook it in the oven or on a stovetop. If using the oven, roast at 350°F (175°C) for about 25-30 minutes, or until it reaches your desired doneness. Let it rest for 10 minutes before slicing thinly.

  3. 3

    Slice the Vegetables

    While the beef is resting, slice the medium tomato into thin slices and wash the lettuce leaves.

  4. 4

    Assemble the Sandwich

    On one slice of bread, layer the sliced beef, followed by caramelized onions, tomato slices, smoked mozzarella cheese, and lettuce. Top with the second slice of bread.

  5. 5

    Serve

    Cut the sandwich in half if desired and serve immediately. Enjoy your delicious roast beef sandwich!
