Cook shells to package directions. Combine Ricotta with 4 to 5 cloves crushed garlic, salt, egg and dried Parmesan. Fill shells with cheese, and place in 13*9 pan. Combine crushed tomatoes with 4 to 5 cloves crushed garlic, onion powder, garlic powder and Italian seasoning. Cover shells with sauce, and top all with mozzarella and Parmesan. Bake at 350 for about 45 minutes, broil for a minute if you would like the cheese to be slightly browned.
