Spinach and Mushroom Stuffed Shells

Spinach and Mushroom Stuffed Shells recipe has three kinds of cheese, melted and gooey, covered in a rich, homemade Marinara sauce. This filling works great with any pasta shape meant to be stuffed and baked, the pasta shape in the photos is named ‘lumaconi’, but a manicotti or conchiglie shape works great as well.
