Preheat oven to 375°. Stir together first 5 ingredients (through basil).
Spoon 1 cup marinara sauce into bottom of an 8-inch-square glass or ceramic baking dish. Top with 2 noodles. Spread 3/4 cup cheese mixture over sauce to cover evenly. Arrange 1 1/2 cups roasted vegetables in 1 layer. Spoon 3/4 cup sauce over vegetables, top with 2 noodles, remaining 3/4 cup cheese mixture, 1 1/2 cups vegetables, 2 noodles, and remaining 1 1/4 cups sauce. Cover with foil, and bake for 20 minutes.
Remove foil, and sprinkle top with mozzarella. Bake in middle of oven for 20 minutes more or until cheese is melted, sauce is bubbling, and noodles are tender.
Let cool for at least 15 minutes before cutting into pieces; serve.
