Preheat your oven to 375°F (190°C).
In a large skillet over medium heat, cook the ground beef until browned. Drain excess fat.
Add the chopped onion, bell pepper, and garlic to the skillet. Cook until vegetables are tender.
Stir in the tomato sauce, diced tomatoes, oregano, basil, salt, and pepper. Let it simmer for about 10 minutes.
Add the cooked pasta to the skillet and mix well.
Transfer the mixture to a greased 9×13-inch baking dish.
Top with shredded mozzarella, grated Parmesan, and your favorite pizza toppings.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
Let it cool for a few minutes before serving.
