First, preheat the oven to 450 ºF. Put the vegetables in a bowl and toss them with olive oil, Italian seasoning, salt, and pepper. Then, spread the tossed veggies in a baking pan, and roast for 15 minutes. In the mean time, boil some water and cook the pasta. Drain the water and add the marinara sauce, ricotta, Parano, and mozzarella cheese to it.
