01 - In a large bowl, whisk together olive oil, cumin, coriander, smoked paprika, turmeric, cinnamon, cayenne pepper, garlic, salt, black pepper, and lemon juice. Add chicken thighs and toss to coat evenly. Cover and refrigerate for at least 20 minutes, up to 2 hours for enhanced flavor.
02 - Rinse basmati rice under cold water until water runs clear. Combine rice, water, salt, and olive oil in a saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 12 to 15 minutes until rice is tender and water is absorbed. Fluff with a fork and keep warm.
03 - Preheat a grill pan or skillet over medium-high heat. Remove chicken from marinade and cook for 5 to 6 minutes per side until golden and cooked through. Allow to rest for 5 minutes, then slice into strips.
04 - While the chicken cooks, dice cucumber, halve cherry tomatoes, thinly slice red onion, chop parsley, and cut lemon into wedges. Arrange mixed salad greens.
05 - Divide rice evenly among four bowls. Top each with salad greens, sliced chicken, hummus, cucumber, tomatoes, red onion, and parsley. Sprinkle sumac over vegetables if desired. Serve with lemon wedges on the side.
06 - In a small bowl, combine Greek yogurt, lemon juice, chopped mint, salt, and pepper. Drizzle over bowls if preferred.
