Method

Preheat the oven to 210°C. On a large rimmed baking sheet, toss together onion, zucchini, squash and bell pepper. Drizzle with olive oil and sprinkle with salt. Toss to coat evenly. Roast the vegetables until brown and tender, for about 30 minutes, stirring once or twice during cooking. Transfer to a serving bowl. While the vegetables are roasting, bring a large pot of salted water to boil. Cook the pasta to al dente then drain and add to the bowl along with lemon zest and juice, olives, pine nuts and parmesan. Stir and toss to coat the pasta with the vegetables. Season with salt and pepper and serve with parmesan sprinkled on top.
