| Red bell pepper (diced) | 1 |
| Mushrooms (sliced) | 8 oz |
| Garlic (minced) | 2 cloves |
| Salt | 1 tsp |
| Black pepper | ½ tsp |
| Smoked paprika (optional) | ½ tsp |

1. Preheat & Prepare:
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.
2. Brown the Beef:
In a large skillet over medium-high heat, cook the ground beef or shaved steak until browned and no longer pink. Drain off any excess fat.
3. Sauté Vegetables:
To the same skillet, add the onion, bell peppers, mushrooms, and garlic. Sauté for about 5–6 minutes, until veggies are softened. Stir in salt, pepper, smoked paprika (if using), and Worcestershire sauce.
4. Layer the Filling:
Spread the beef and vegetable mixture evenly in the bottom of your prepared baking dish.
5. Mix the Creamy Topping:
In a mixing bowl, beat together the cream cheese, mayonnaise, and eggs until smooth and fully combined.
6. Assemble the Casserole:
Pour the creamy mixture evenly over the meat and veggies. Sprinkle the top with the provolone and mozzarella cheese.
7. Bake to Perfection:
Place in the oven and bake for 25–30 minutes, or until the top is golden and bubbling.
8. Rest & Serve:
Allow the casserole to rest for about 5 minutes before slicing and serving. Enjoy it on its own or pair it with a fresh green salad, crusty bread, or toasted hoagie rolls for a sandwich-style experience.
