Preheat your oven to 425°F (220°C).
In a small bowl, mix the cumin, paprika, garlic powder, salt, and pepper.
Pat the chicken breast dry and coat it evenly with the spice blend.
Place the chicken on a lightly greased or parchment-lined baking sheet. Roast in the oven for about 20-25 minutes or until cooked through, turning once halfway if desired.
While the chicken is baking, chop the bell pepper, zucchini, and red onion into bite-size pieces.
In a mixing bowl, toss the vegetables with olive oil, a pinch of salt, and a little extra paprika if desired. Spread them out on another baking sheet.
Roast the vegetables in the oven for about 15-20 minutes until tender and slightly charred.
Heat the chickpeas briefly in a small saucepan or microwave until warm, seasoning with a pinch of salt and pepper.
Slice the cooked chicken breast and assemble your bowl by layering the roasted chicken, vegetables, and chickpeas.
Finish with an extra drizzle of olive oil or a squeeze of lemon if desired. Serve warm and enjoy!
