Ingredients

* 8 submarine or hoagie buns (8 inches)
* 1 pound ground beef
* 1 cup spaghetti sauce
* 1 tablespoon garlic powder
* 1 tablespoon Italian seasoning
* 1 cup ricotta cheese
* 1/4 cup grated Parmesan cheese
* 1 cup (4 ounces) shredded cheddar cheese, divided
* 1 cup (4 ounces) shredded part-skim mozzarella cheese, divided

Directions

* Make a 2-in.-wide V-shaped cut in the center of each bun to within 1 inch of the bottom. Remove cut portion and save for another use; set aside.
* In a large skillet, cook beef over medium heat until no longer pink; drain. Add the spaghetti sauce, garlic powder and Italian seasoning. Cook 4-5 minutes or until heated through.
* Meanwhile, combine the ricotta, Parmesan cheese and half of cheddar and mozzarella cheeses. Spoon meat sauce into buns; top with cheese mixture. Place on a baking sheet. Cover loosely with foil.
* Bake at 350° for 20-25 minutes. Uncover; sprinkle with remaining cheddar and mozzarella. Return to the oven for 2-3 minutes or until the cheese is melted. Yield: 8 servings.
