Ingredients
  

Meat and Dairy

  • 2 lbs ground beef (80/20 fat ratio preferred) Use halal-certified ground beef if required.
  • 8 oz cream cheese, softened to room temperature
  • 8 oz provolone cheese, sliced or torn into pieces
  • 1.5 cups mozzarella cheese, shredded

Vegetables

  • 1 large onion, diced
  • 2 large bell peppers (green, red, or mixed), diced
  • 2 cloves garlic, minced

Seasonings and Oils

  • 2 tbsp Worcestershire sauce
  • 1 tbsp olive oil
  • Salt and pepper, to taste

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray. Heat olive oil in a large skillet over medium heat.
  • Add diced onions and bell peppers to the hot oil, cooking for 5–6 minutes until they start to soften and become fragrant.
  • Add minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.
  • Add ground beef to the skillet, breaking it up as it cooks. Season generously with salt and pepper, cooking for 7–8 minutes until completely browned with no pink remaining.
  • Stir in Worcestershire sauce and let it coat the meat mixture for enhanced flavor. Reduce heat to low and add the softened cream cheese, stirring until completely melted and creamy.

Assembly and Baking

  • Transfer the mixture to your prepared baking dish and spread evenly. Layer torn provolone pieces over the beef, then top with shredded mozzarella.
  • Bake for 22-25 minutes until cheese is melted, bubbly, and lightly golden on top. Let rest for 5 minutes before serving.

Notes

For variations, add spiciness with jalapeños, substitute mushrooms, or use different cheeses. Serve with cauliflower rice or a salad for a lighter meal. Leftovers can be refrigerated for 3–4 days or frozen for up to 3 months.
