This recipe is so easy, once you prepare it, you will never buy store bought shells again! Preparing the crepes and filling them yourself isn't as hard as it seems. Once you make this recipe you will never buy those store bought shells ever! You can take the Prosciutto out and make the filling with just the cheese. You can even fill the crepes with any other kind of filling you make. Experiment and make different fillings with an assortment of cheeses, vegetables or seafood! This recipe makes alot of Manicotti. Alot of times i will make extra Manicotti and after rolling them, I place them on a baking sheet and put them in the freezer till they are frozen. I then transfer them into a ziplock freezer bag and they can stay in the freezer for up to 3 months. Then when you want to cook them, all you do is layer sauce on the bottom of your pan, place the frozen Manicotti on top of the sauce, cover them with more sauce, cover with foil tightly and bake in a 350 degree oven for about 1hr. take the foil off and cover with shredded Mozarella and bake till melted. Delicious! Enjoy and remember to experiment with your own fillings!....I also use store bought Marinara sauce if I don't have my own on hand.
