directions

Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

In a large skillet over medium heat, add olive oil and sauté the diced onions and bell peppers until softened, about 5 minutes.

Push the vegetables to the side of the pan and add the ground beef. Cook until browned and no longer pink, breaking it apart as it cooks.

Drain excess grease, then mix the vegetables and beef together. Stir in the cream cheese until melted and fully combined.

Season the mixture with salt, pepper, and Italian seasoning to taste.

In a small bowl, whisk the eggs and pour them into the beef mixture. Stir well to combine.

Transfer the mixture to the prepared baking dish and top with shredded provolone or mozzarella cheese.

Bake for 20-25 minutes, or until the cheese is bubbly and slightly golden on top.

Let the casserole sit for 5 minutes before serving.
