Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the zucchini into half-moons, chop the red bell pepper into bite-sized pieces, and thinly slice the red onion.
Place the vegetables on the baking sheet and toss with half of the olive oil, sea salt, black pepper, and dried oregano.
Roast the vegetables in the oven for 18 to 20 minutes until they are tender and show slight caramelization on the edges.
While the vegetables roast, bring a medium pot of salted water to a boil and cook the chickpea pasta according to the package directions until al dente.
Drain the pasta, reserving two tablespoons of the cooking water, and set aside.
Heat the remaining olive oil in a large skillet over medium-high heat and add the sliced chicken sausage and minced garlic.
Sauté the sausage for 4 to 5 minutes until it is browned and heated through.
Add the roasted vegetables, cooked pasta, and reserved pasta water to the skillet, tossing gently to combine all ingredients.
Serve the dish warm, garnished with the grated parmesan cheese for a savory finish.
