Pre-heat oven to 325°F; if using a Pyrex baking dish; otherwise, pre-heat the oven to 350°F.
In boiling salted water, cook the pasta just to al dente; remove from heat, drain and set aside.
Grease the bottom and sides of a large casserole dish.
Place half of the cooked rotini pasta in the bottom of the dish.
Layer the casserole with half the turkey, half the parmesan cheese, half the bacon, and half the sauce; repeat these layers and top with the grated mozzarella cheese.
Place in pre-heated oven and bake for about 45 minutes to an hour or until the casserole is bubbling and the top is golden brown.
