Turkey stuffed shells

These pasta shells are so yummy!! I love to make these as often as I can. If your shells start to break when filling them, feel free to just let it be a casserole. Ha! It's still just as good!

16 Oz jumbo pasta shells
1 lb lean ground turkey breast
1/2 cup liquid egg substitute
2/3 cup chopped onion
1 clove garlic, minced
3/4 tsp dried oregano
3/4 tsp salt
1/4 tsp ground black pepper
1 1/2 cups ( 6 ounces) shredded part-skim mozzarella cheese
1/2 cup chopped fresh spinach
1 jar (26 ounces) marinara sauce
1/4 cup grated Parmesan cheese
Directions

1.Preheat the oven to 350°F. Coat a 13" x 9" baking dish with cooking spray.
2.In a large pot of boiling salted water, cook the pasta for 8 minutes, drain, and set aside.
3.In a large skillet over medium-high heat, cook the turkey for 5 to 10 minutes, or until no longer pink, breaking it up with the back of a spoon. Set aside.
4.In a large bowl, combine the egg substitute, onion, garlic, oregano, salt, pepper, and 1/2 cup of the mozzarella and mix well. Add the cooked turkey and spinach and mix well.
5.Spread the bottom of the prepared baking dish with a layer of marinara sauce. Fill the shells with equal portions of the turkey mixture, arranging them in the baking dish as you go. When all the shells are filled, cover with the remaining marinara sauce and mozzarella. Sprinkle the Parmesan cheese on top.
6.Bake, covered, for 45 minutes, then uncover and bake for 15 minutes longer. Let stand for 5 to 10 minutes before serving.
