Preheat your oven to 350°F (175°C).
In a skillet over medium heat, brown the ground beef and Italian sausage until fully cooked. Drain excess fat.
Stir in garlic powder, onion powder, oregano, basil, salt, and pepper. Mix well.
In a large mixing bowl, combine the cooked pasta, pizza sauce, cooked meat mixture, bell pepper, mushrooms, pepperoni, and half of the mozzarella cheese.
Pour the mixture into a greased 9x13 inch baking dish. Spread it evenly.
Top with the remaining mozzarella cheese and crumbled bacon.
Cover with aluminum foil and bake for 30 minutes.
Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
Allow to cool slightly before serving. Cut into squares and enjoy!
