First, cook the ziti until al dente in a big pot of salted water.
Meanwhile, mix the ricotta cheese with the oregano and set it aside.
In a large pot or skillet, warm the meat sauce or sauce of your choice up over medium low heat.
Once the ziti is done cooking, strain it from the water and add it to the meat sauce.
Now add in 1 c of the shredded mozzarella cheese and give everything a nice big mix then add it to a baking dish.
Next, using a spoon make little pockets in the ziti and place a heaping tablespoon on the ricotta mixture inside the hole and cover it with the pasta.
Keep making evenly spread out little holes and filling them with the ricotta mixture.
Now sprinkle the top of the ziti with Parmesan cheese and the rest of the mozzarella cheese.
Then bake it, covered, until the cheese is melted and the sizes are nice and bubbly. (See my tip for keeping the cheese from sticking above)
Finally let it cool slightly, garnish with basil (optional) and serve warm. Enjoy!
