Preheat oven to 425°F (220°C).
In a large bowl, combine chicken, onion, bell pepper, carrots, and chickpeas.
Drizzle with olive oil and add all spices and salt.
Toss everything until evenly coated.
Spread mixture onto a sheet pan in a single layer.
Roast for 30–35 minutes until chicken is fully cooked and vegetables are tender.
Broil for 2 minutes at the end for a slight char if desired.
Remove from oven and serve warm. This Chicken Shawarma Sheet Pan Dinner pairs perfectly with tzatziki.
