Preheat oven to 350 degrees. Cook manicotti pasta as package directs, drain, and place in cool water while mixing the cheeses.
In a medium bowl, combine Ricotta cheese, 1 cup Mozzarella cheese, Provolone cheese, Parmesan cheese, egg, garlic powder, oregano and basil; mix well.
Spread half the sauce on the bottom of a greased 13 x 9 inch baking dish. Stuff cheese mixture into manicotti. Arrange manicotti over sauce. Spoon remaining sauce over manicotti. NOTE: At this stage the dish can be frozen for use later. To use, completely thaw in refrigerator 24 hours and follow baking instructions below.
Cover and bake 35 minutes or until hot and bubbly. Uncover and top with remaining 1 cup Mozzarella cheese. Bake a few minutes longer until cheese melts.
