Prep time: 15 minutes. Cook time: 30 minutes.
Preheat oven to 450F.
Layer zucchini, squash, eggplant and purple onion on a single layer on a baking sheet. Drizzle with 2 tablespoons olive oil, 1/4 teaspoon salt and 1/4 teaspoon pepper. Roast vegetables, stirring occasionally, 30 minutes or until tender.
Meanwhile, layer tomatoes on a small baking sheet or baking dish. Sprinkle with remaining olive oil and remaining salt. Bake in preheated oven for 30 minutes.
Toss cooked pasta with eggplant mixture and tomatoes. Add remaining pepper, balsamic vinegar, cheese and herbs. Serve immediately.
Note: This also tastes great cold so cover and refrigerate any leftovers.
