01 - Preheat oven to 400°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, toss the drained chickpeas with olive oil, cumin, smoked paprika, coriander, turmeric, cinnamon, black pepper, garlic powder, onion powder, cayenne (if using), and salt until evenly coated. Spread in a single layer on the prepared baking sheet. Roast for 20–25 minutes, shaking the pan halfway through, until the chickpeas are golden and crisp.
03 - While the chickpeas roast, whisk together tahini, lemon juice, water, minced garlic, salt, and olive oil in a small bowl until smooth. Add additional water, 1 tbsp at a time, until the sauce reaches a drizzle-able consistency.
04 - Halve the cherry tomatoes, dice the cucumber, thinly slice the red onion, shred the lettuce, and chop the fresh parsley. Set aside.
05 - Divide the cooked grain or cauliflower rice among 4 bowls. Arrange the lettuce, cucumber, tomatoes, red onion, pickled cabbage, and parsley over the base. Top each bowl with the roasted chickpeas.
06 - Drizzle each bowl generously with tahini sauce. Serve immediately with lemon wedges on the side.
