01 - Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - In a mixing bowl, toss drained chickpeas with olive oil, ground cumin, smoked paprika, ground coriander, turmeric, cayenne pepper, garlic powder, onion powder, salt, and black pepper until evenly coated.
03 - Spread seasoned chickpeas in a single layer on the prepared baking sheet. Roast for 20–25 minutes, stirring halfway through, until golden and slightly crispy.
04 - While chickpeas roast, whisk together tahini, lemon juice, minced garlic, and salt in a small bowl. Gradually add water, 1 tablespoon at a time, until the sauce is smooth and pourable.
05 - Divide cooked brown rice or quinoa among four bowls. Top each with roasted chickpeas, chopped cucumber, halved cherry tomatoes, thinly sliced red onion, shredded lettuce or mixed greens, and pickled red cabbage.
06 - Drizzle each bowl generously with tahini sauce. Garnish with chopped fresh parsley or cilantro and serve immediately with lemon wedges on the side.
