Method

Roast Preparation

  1. 1

    Season the Beef

    Preheat your oven to 300°F (150°C). Rub the beef roast with olive oil, then season it generously with salt, black pepper, garlic powder, and onion powder on all sides.

  2. 2

    Roast the Beef

    Place the seasoned beef roast in a roasting pan. Roast in the preheated oven for about 3-4 hours, or until the internal temperature reaches 135°F (57°C) for medium-rare. Once done, remove from the oven and let it rest for 15-20 minutes before slicing.

Vegetable Preparation

  1. 3

    Sauté Onions and Mushrooms

    In a skillet, heat a tablespoon of olive oil over medium heat. Add the sliced onion and sauté until translucent, about 5 minutes. Then add the sliced mushrooms and continue to sauté until they are tender and browned, about 5-7 minutes more. Season with salt and pepper to taste.

Sandwich Assembly

  1. 4

    Slice the Beef

    After the beef has rested, slice it thinly against the grain.

  2. 5

    Assemble the Sandwich

    Cut the French rolls in half. Layer the bottom half with sliced roast beef, followed by the sautéed onions and mushrooms. Top with shredded cheddar cheese and a handful of mixed greens. Place the top half of the roll on the sandwich.

Serving

  1. 6

    Serve

    Serve the roast beef sandwiches warm. Optionally, you can melt the cheese by placing the assembled sandwiches under a broiler for 1-2 minutes before serving.
