Preheat your oven to 400°F (200°C).
Dice the chicken breast into bite-sized pieces and chop the zucchini and red bell pepper into 1-inch chunks.
On a large sheet pan, toss the chicken, zucchini, pepper, and minced garlic with olive oil, sea salt, black pepper, and red pepper flakes.
Roast in the oven for 15-18 minutes until the chicken is cooked through and the vegetables are tender and slightly caramelized.
While the vegetables roast, cook the chickpea pasta in boiling salted water according to package directions, then drain.
In a small baking dish, combine the cooked pasta, roasted chicken, roasted vegetables, and marinara sauce.
Stir in the fresh lemon zest to brighten the flavors.
Top the mixture with parmesan cheese and return to the oven for 5 minutes, or until the cheese is melted and golden.
Serve immediately while hot.
