01 - Preheat the oven to 400°F. Line a large baking sheet with parchment paper.
02 - In a large mixing bowl, toss the drained chickpeas with olive oil, cumin, smoked paprika, coriander, turmeric, cinnamon, black pepper, garlic powder, onion powder, cayenne pepper (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 the tahini, lemon juice, water, minced garlic, salt, and olive oil in a small bowl until completely smooth. Add additional water, 1 tbsp at a time, until the sauce reaches a pourable, drizzly consistency.
04 - Halve the cherry tomatoes, dice the cucumber, thinly slice the red onion, chop the fresh parsley, and shred or portion the lettuce and pickled cabbage. Set aside.
05 - Divide the cooked rice or grain of choice among 4 bowls. Arrange the roasted chickpeas, lettuce, cucumber, tomatoes, red onion, pickled cabbage, and parsley over each portion.
06 - Drizzle each bowl generously with the prepared tahini sauce. Serve immediately with lemon wedges on the side.
