Preheat the oven to 425°F. Spread out the chopped vegetables on 2 baking sheets— you want them spread out enough so they don't steam. Toss with olive oil, salt, and pepper. Roast for 20 minute, stirring halfway through.
While the vegetables roast, start the pasta. Bring a pot of water to boil with the salt. Cook the pasta as instructed. Prior to straining, reserve ½ cup pasta water.
Over low heat, add the pasta back into the pot. Stir in the marinara sauce, mozzarella cheese, parmesan cheese, and water. Then stir in the fresh basil. Garnish with additional parmesan cheese, if desired.
