pasta shells florentine

I spotted this recipe on my friend Jackie's blog a while back and bookmarked it to try. I finally got around to making it last month and I am so glad that I did. It is really simple to put together and it tastes wonderful. Definitely a recipe that will be in heavy rotation around our house.

Need

• 10 oz. frozen spinach 
• 2 cups shredded mozzarella cheese 
• 2 cups cottage cheese 
• 2 T. parmesan cheese 
• 2 egg whites 
• 1 box jumbo pasta shells, cooked 
• 1 jar of your favorite spaghetti sauce

Make

Mix cheeses, spinach and egg whites. Stuff into cooked shells and arrange into a 9×13 pan. Cover with spaghetti sauce. Bake at 375 for 30-40 minutes.
