Step 1

Cook the pasta shells according to the package directions. Drain the pasta, rinse it in cold water and set it aside.

Step 2

In a large bowl, combine the ricotta, broccoli, mozzarella, egg whites, basil, garlic salt and pepper. Set this aside as well.

Step 3

Preheat the oven to 375°F. Spread half the spaghetti sauce into a 13x9-inch baking dish coated with cooking spray. Stuff the pasta shells with the ricotta mixture, then arrange the shells over the spaghetti sauce. Pour the remaining sauce over the pasta.

Step 4

Cover the dish and bake it for 25 minutes. Uncover the dish, sprinkle the Parmesan cheese over the pasta, then bake it again until heated through, about five minutes longer.
