1 pound ground beef
1 16-ounce package rotini noodles
1/2 cup chopped onion
2 eggs
1/3 cup Parmesan cheese
1/4 cup butter, melted
1/2 teaspoon garlic powder
1 16-ounce jar meatless spaghetti sauce (I use homemade canned sauce)
1 8-ounce can mushrooms (or use fresh if you prefer)
1-2 teaspoons pizza seasoning, optional (I use Wildtree’s Pizza Sauce seasoning)
1 package pepperoni
2 cups shredded mozzarella cheese

Combine the eggs, Parmesan cheese, garlic powder and melted butter in a large bowl. Set aside.

Cook rotini noodles per package instructions. Add cooked noodles to the egg and Parmesan cheese mixture. Toss noodles to coat. Set aside.

Cook ground beef with the onions until the beef is completely brown. Drain. Add spaghetti sauce and mushrooms, and cook on low for 5-10 minutes or until the sauce is well combined and slightly thickened. Add meat mixture to the cooked noodle mixture. Add pepperoni slices, reserving some to place on the top of the casserole. Mix all ingredients until well combined.

Place mixture into a greased 9 x 13-inch baking dish. Top casserole with remaining pepperoni slices and the 2 cups of shredded mozzarella cheese. Bake covered in a 350 degrees Fahrenheit oven for 30 minutes. Uncover and bake for an additional 10 minutes, or until cheese is melted and bubbly.
