01 - Preheat oven to 425°F. Thoroughly pat chickpeas dry with paper towels to remove excess moisture, which helps them crisp up during roasting.
02 - In a large bowl, combine chickpeas with olive oil, chili powder, smoked paprika, cumin, garlic powder, sea salt, lime zest, and lime juice. Toss until evenly coated.
03 - Spread seasoned chickpeas on a parchment-lined baking sheet in a single layer. Roast for 20–25 minutes, shaking the pan halfway through cooking, until golden brown and crispy.
04 - While chickpeas roast, combine green cabbage, red cabbage, carrots, red bell pepper, and cilantro in a large mixing bowl.
05 - In a small bowl, whisk together olive oil, lime juice, maple syrup, chili powder, cumin, sea salt, and minced garlic until emulsified and smooth.
06 - Pour dressing over the slaw mixture and toss thoroughly to coat all vegetables evenly.
07 - Divide dressed slaw among four serving bowls. Top each portion with crispy roasted chickpeas, avocado slices, and green onions.
08 - Serve immediately with fresh lime wedges on the side for squeezing over the bowl.
