Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Dice the chicken breast into 1-inch cubes and chop the zucchini and red bell pepper into bite-sized pieces.
Place the chicken and vegetables on the baking sheet, then toss with olive oil, minced garlic, sea salt, and black pepper.
Roast in the oven for 18-20 minutes until the chicken is fully cooked and the vegetables are tender and slightly caramelized.
While the tray roasts, cook the chickpea pasta in a pot of boiling water according to the package instructions, then drain and set aside.
In a small mixing bowl, whisk together the plain Greek yogurt, lemon juice, and lemon zest until smooth.
Transfer the cooked pasta, roasted chicken, and vegetables into a large mixing bowl.
Fold in the lemon-yogurt sauce, stirring gently to ensure the pasta and vegetables are evenly coated.
Top with freshly chopped parsley and serve immediately while warm.
