    Prepare the Roast Beef

    In a saucepan, heat the garlic au jus sauce over medium heat. Add the roast beef slices and simmer for about 10 minutes until heated through.

    Sauté the Vegetables

    In a skillet, heat olive oil over medium heat. Add sliced red onion and diced green bell pepper. Sauté for about 5-7 minutes until softened. Add diced roma tomatoes and cook for an additional 2 minutes. Season with salt and black pepper.

  4. 4

    Toast the Sub

    Place the assembled hoagie buns on a baking sheet and toast in the preheated oven for about 5-7 minutes or until the cheese is melted and bubbly.
