01 - Preheat oven to 400°F. Line a large baking sheet with parchment paper.
02 - Pat the drained chickpeas dry with a clean kitchen towel. In a mixing bowl, toss them with olive oil, cumin, smoked paprika, coriander, turmeric, cayenne (if using), garlic powder, onion powder, salt, and black pepper until every chickpea is evenly coated.
03 - Spread the seasoned chickpeas in a single layer on the prepared baking sheet. Roast for 20–25 minutes, stirring halfway through, until they are golden brown and slightly crispy on the outside.
04 - While the chickpeas roast, whisk together the tahini, lemon juice, minced garlic, and salt in a small bowl. Gradually add water, one tablespoon at a time, until the sauce reaches a smooth, pourable consistency.
05 - Divide the cooked rice or quinoa among four bowls. Arrange the roasted chickpeas, chopped cucumber, halved cherry tomatoes, sliced red onion, shredded greens, and pickled cabbage over each portion.
06 - Drizzle each bowl generously with the tahini sauce. Garnish with chopped parsley or cilantro and serve immediately with lemon wedges on the side.
