Cook the Pasta - Bring a large pot of salted water to a boil and cook the pasta according to the package directions until just al dente. Drain and set aside.
Brown the Meat - In a large skillet over medium heat, cook the ground beef until no longer pink, breaking it up with a spoon. Drain excess grease.
Add Veggies and Sauce - Add the diced onion and bell pepper to the skillet. Sauté for 3-4 minutes until softened. Stir in sloppy joe sauce, diced tomatoes, garlic powder, salt, and black pepper. Let simmer for 5 minutes.
Assemble the Casserole - In a large mixing bowl, combine the cooked pasta, sloppy joe meat mixture, and half of the cheddar cheese. Transfer to a greased 9x13 casserole dish.
Add Cheese and Bake - Top with the remaining cheddar cheese and all the mozzarella. Bake for 20 minutes or until the cheese is bubbly and golden.
Garnish and Serve - Remove from the oven, let cool slightly, and sprinkle with fresh parsley before serving.
