04 - Spread the seasoned chickpeas in a single layer on the prepared baking sheet.
05 - Roast for 25 to 30 minutes, shaking the pan halfway through, until the chickpeas are golden brown and crisp.
06 - Allow the chickpeas to cool slightly before serving warm or at room temperature, garnished with chopped cilantro and a squeeze of lime if desired.
