Spinach Stuffed Shells

1 pkg. jumbo pasta shells
1 jar favorite spaghetti sauce
1pkg chopped spinach, thawed
2 cups mozzarella cheese, shredded
1/3 cup parmesan cheese, shredded
1 lg carton cottage cheese
1 egg white

Thaw spinach and drain well. Cook shells according to the package directions ( I always slightly undercook them by a minute). Mix in a large bowl; cottage, cheese, mazzarella, parmesan, spinach and egg white. Stuff mixture into shells and place in 9X13 baking dish (I usually use 2 smaller sized ones because my family does not eat a whole 9X13 for dinner.) I spray the baking dish with cooking spray and pour a little bit of sauce in the bottom. Stuff mixture into shells and place into prepared dish (or dishes). Pour spaghetti sauce over shells. Cover and freeze or you can bake it immediatly at 350 for 30-45 minutes until heated thru. If you freeze it plan on adding an additional hour to your baking time. I love freezing this meal, but it is also a great recipe to make earlier in the day and keep in the fridge. Then all you have to do is throw it in the oven for dinner.
