Preheat the oven to 350 degrees
Heat 2 tablespoons of olive oil in a large skillet or dutch oven over medium heat
Start boiling the water for the ziti in another pan, or do this first and set the cooked pasta aside while you work on the vegetables
Add the onion, garlic, zucchini, red bell pepper to the skillet with the oil. Cook for around 10 minutes, until softened. Add the pasta sauce and salt and let it simmer for 5 more minutes while the ziti finishes cooking
In a small bowl, mix together 1 cup of ricotta cheese with the ½ cup of fresh chopped basil and one cup of fresh grated parmesan cheese
Once the ziti is cooked, drain and mix it together with the sauce and vegetables. Remove from the heat.
Spray a 9 by 13 baking casserole dish with olive oil or other cooking spray
Add half of the sauce/noodles to the casserole dish and spread it out
Spread out all of the ricotta/parmesan/basil mixture over the top of the ziti
Top with the remaining 1 cup of fresh grated parmesan cheese
Add the remaining half of the pasta/sauce
Top with 8 oz of shredded mozzarella
Cover the dish with foil and bake for 10 minutes at 350
Remove the foil and bake for another 20 minutes, until bubbly
For a little browned cheese on top, broil for 1-2 minutes at the end. Watch closely to avoid burning
