🧂 Ingredients

• 1 lb thinly sliced beef (ribeye or sirloin recommended)
• 1 medium onion, sliced
• 1 green bell pepper, sliced
• 1 red bell pepper, sliced
• 2 cups shredded provolone or mozzarella cheese
• 1 cup shredded cheddar cheese (optional, for extra cheesiness)
• 1 tablespoon olive oil
• Salt and pepper, to taste
• 1 teaspoon garlic powder
• 1 teaspoon Worcestershire sauce
• 4–6 hoagie rolls or sub rolls, cubed (optional, for a more “casserole bread” texture)

👩‍🍳 Instructions

1. Preheat oven:
   • Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
2. Cook the vegetables:
   • In a large skillet, heat olive oil over medium heat. Sauté onions and bell peppers until softened and slightly caramelized. Remove from skillet and set aside.
3. Cook the beef:
   • In the same skillet, add beef, salt, pepper, garlic powder, and Worcestershire sauce. Cook until browned and just cooked through.
4. Assemble the casserole:
   • If using bread, layer cubed rolls in the bottom of the baking dish. Spread cooked beef evenly over the bread (or directly in the dish if skipping the bread). Top with sautéed peppers and onions. Sprinkle shredded cheeses evenly over the top.
5. Bake:
   • Bake for 20–25 minutes, or until cheese is melted and bubbly. Optional: broil for 1–2 minutes to get a golden, crispy cheese topping.
6. Serve:
   • Let casserole rest for 5 minutes before serving. Scoop portions onto plates and enjoy the melty, savory goodness!
