Begin by cooking your rigatoni until just al dente. (It will cook more in the oven and you don't want it too mushy!)
In the meantime, preheat your oven to 350.
Next, start laying down your meats on the bottom of a pyrex dish.
Next, in a large mixing bowl, gently stir pasta sauce together with half a container of cottage cheese (or about 12 oz), just until loosely combined.
Strain cooked pasta and add to the bowl of sauce/cheese. Spoon into the pyrex dish to cover the meat.
Top with an 8 oz bag of shredded Mozzarella, and then sprinkle about 1/4 cup of parmesan cheese on top of that. If you like, you can layer even more meats on top.
Bake for 350 for 20-30 minutes or until the cheese on top is turning golden.
