Preheat the oven to 400F.

Heat a big pot of water to boiling, and cook the pasta 1-2 minutes less than the directions state. Don't forget to salt the water!

While the pasta cooks, drain the mozzarella, and cut the bites into fourths.

When the pasta is ready, drain and return to the pot. Stir in the tomato sauce.

Grab a 8x8 baking dish, lightly coat with olive oil, and pour in about half of the pasta and sauce.

Sprinkle the pasta with half of the ham, mozzarella, and Parmesan cheese.

Pour the rest of the pasta in the dish, and top with the remaining ham and cheese.

Place in oven, and bake for about 20-25 minutes, until the cheese is nice and melted and the corners of the dish are golden and crusty!

Let cool slightly and serve!
