Heat oven to 400F.

In a 9×9 baking disk, cover the bottom in a thin layer of sauce and then layer in shredded mozzarella cheese, baby spinach, pepperoni, gnocchi, the rest of the pasta sauce, pepperoni, mozzarella cheese, and pepperoni.

Cover the dish in tinfoil and bake for 15 minutes in the middle rack.

When done, remove the tinfoil and broil for 5 minutes or until the top layer of cheese has melted and pepperoni is crisp to your liking.
