These were made with ingredients I had on hand from the recipe at skinnytaste.com...one of my new favorite places to get recipes. I made a couple of changes...just used store bought Italian bread crumbs and used egg whites instead of wasting a whole egg, since I always have a container of egg whites in the fridge. The thing I didn't do was freeze the mozzarella sticks long enough. Some of the sticks melted in spots and didn't hold their shape. Just be sure to freeze them through and you will be happy.
I used homemade marinara, but you can use whatever your family likes. Enjoy!
