Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray.
In a large skillet, heat olive oil over medium heat. Add diced onions and bell peppers, cooking for about 5-6 minutes until softened.
Add minced garlic and ground beef to the skillet. Cook for 7-8 minutes until browned, draining excess fat if necessary.
Stir in Worcestershire sauce and cook for 1-2 minutes. Then, reduce heat and add softened cream cheese, stirring until melted.
Transfer the beef mixture into the prepared baking dish. Layer torn provolone over the beef, then top with shredded mozzarella.
Bake for 22-25 minutes until cheese is bubbly and lightly golden. Let rest for 5 minutes before serving.
