Spinach Stuffed Shells

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

Thaw spinach and drain well. Cook shells according to package directions (I undercooked by 1-2 minutes)

In a large bowl mix together the cottage cheese, mozzarella, Parmesan, spinach, and egg white. Stuff mixture into shells and place in 9x13 baking dish that has been sprayed with cooking spray. Pour spaghetti sauce over shells and bake for 30-45 minutes.

When I made this I used 2 smaller baking dishes and froze half. If you freeze it, plan on adding an additional hour to your baking time.
