01 - In a large bowl, whisk together olive oil, lemon juice, minced garlic, cumin, smoked paprika, oregano, salt, and black pepper. Add chicken cubes and toss to coat evenly. Marinate for at least 20 minutes, or refrigerate up to 2 hours for deeper flavor penetration.
02 - While chicken marinates, combine chickpeas, tahini, lemon juice, olive oil, garlic, cumin, and salt in a food processor. Blend until completely smooth, scraping down sides as needed. Add water one tablespoon at a time until creamy and spreadable. Taste and adjust seasoning.
03 - Preheat grill or grill pan to medium-high heat (approximately 400°F). Remove chicken from marinade and thread pieces onto skewers, leaving slight space between pieces for even cooking.
04 - Place skewers on preheated grill and cook for 12-15 minutes, turning every 3-4 minutes to achieve even char on all sides. Chicken is done when internal temperature reaches 165°F and pieces are lightly browned.
05 - Spread prepared hummus generously across a serving platter. Arrange grilled skewers on top of hummus bed. Sprinkle with fresh parsley and serve immediately with lemon wedges, pita bread, and fresh vegetables on the side.
