Preheat the oven to 425°F and line a large rimmed baking sheet if desired.
Cut the vegetables into similar-size pieces so they roast evenly.
In a large bowl, combine the olive oil, garlic, lemon juice, and spice blend.
Add the chicken and toss to coat well.
Add the vegetables and chickpeas and toss until everything is evenly coated with the spiced oil mixture.
Spread the vegetables and chickpeas across the pan, then nestle the chicken on top, skin-side up if using skin-on thighs, leaving some space for browning.
Roast for 25 minutes, rotate the pan, then roast 10 to 20 minutes more until the chicken reaches at least 165°F and the vegetables are browned and tender.
If needed, remove the chicken once done and roast the vegetables 5 to 8 minutes longer.
Finish with fresh lemon before serving.
