Follow the package instructions to cook the Banza protein pasta (or your chosen pasta) until it's al dente. Remember, the pasta will continue cooking in the oven, so you don't want it to be too soft.

In a large skillet over medium heat, cook the ground meat until it's browned and cooked through. Add the onions and bell pepper to the skillet with the cooked meat and sauté. Once translucent, add minced garlic and cook until fragrant (about 1-2 minutes)

Pour the spaghetti sauce into the skillet with the meat, onions, and garlic. Add the dried Italian seasoning, salt, and pepper. Stir the mixture well.

Once the pasta is cooked, drain it and add it to the skillet with the meat and sauce. Gently toss everything together, ensuring the pasta is evenly coated in the flavorful sauce.

Transfer the pasta and sauce mixture into a 9x13 inch baking dish. Sprinkle shredded mozzarella cheese generously over the top, and finish it off with a sprinkle of grated Parmesan for that extra layer of flavor.

Place the baking dish in the preheated oven and bake for approximately 25-30 minutes or until the cheese is melted and bubbly, and the top is golden brown.

Once out of the oven, let the casserole cool for a few minutes. Garnish with fresh parsley if desired, then slice and serve your Baked Spaghetti Casserole.
