Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Cut the chicken breast, zucchini, and red bell pepper into bite-sized pieces.
Place the chicken and vegetables on the baking sheet, drizzle with olive oil, and season with sea salt and black pepper.
Roast in the oven for 15 to 18 minutes, or until the chicken is cooked through and the vegetables are slightly browned.
While the vegetables roast, cook the chickpea pasta in boiling water according to the package directions until al dente.
Drain the pasta, reserving about two tablespoons of the cooking water.
In a large mixing bowl, combine the cooked pasta, roasted chicken, and vegetables.
Add the minced garlic, chopped fresh parsley, and lemon juice, tossing thoroughly to combine all flavors.
If the pasta seems dry, add the reserved pasta water one tablespoon at a time until the desired consistency is reached.
