Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Chop the zucchini and red bell pepper into bite-sized pieces, halve the cherry tomatoes, and dice the chicken breast into 1-inch cubes.
Place the chicken and vegetables on the prepared baking sheet, drizzle with olive oil, and season with sea salt and black pepper.
Toss everything together until evenly coated, then spread into a single layer and roast for 15-18 minutes until the chicken is cooked through.
While the tray roasts, bring a medium pot of salted water to a boil and cook the chickpea pasta according to package directions, then drain.
Mince the garlic and finely chop the fresh parsley while the pasta finishes.
In a large mixing bowl, combine the cooked pasta with the roasted chicken and vegetables, including any juices from the pan.
Stir in the minced garlic, fresh parsley, and lemon juice, tossing well to create a light, aromatic sauce before serving.
