Preheat your oven to 400°F and line a baking sheet with parchment paper.
Slice the zucchini into half-moons and chop the red bell pepper into bite-sized pieces.
Toss the zucchini and bell peppers on the baking sheet with olive oil, sea salt, black pepper, and garlic powder.
Roast the vegetables for 15 to 18 minutes until they are tender and slightly caramelized around the edges.
While vegetables roast, boil the chickpea pasta in a pot of salted water according to package instructions.
Before draining the pasta, reserve 2 tablespoons of the starchy pasta water.
In a large mixing bowl, whisk together the plain Greek yogurt, grated parmesan cheese, and the reserved pasta water to create a smooth sauce.
Add the cooked pasta, shredded rotisserie chicken breast, and roasted vegetables to the bowl.
Toss everything together until the pasta is well-coated in the creamy sauce.
Garnish with chopped fresh parsley and serve immediately.
