01 - Whisk together olive oil, lemon juice, minced garlic, cumin, smoked paprika, oregano, salt, and black pepper in a large bowl. Add chicken cubes and toss thoroughly to coat. Marinate for minimum 20 minutes, maximum 2 hours refrigerated.
02 - Process chickpeas, tahini, lemon juice, olive oil, garlic, cumin, and salt in a food processor until completely smooth. Gradually incorporate water, one tablespoon at a time, until desired creamy consistency is achieved. Taste and adjust seasoning as necessary.
03 - Preheat grill or grill pan to medium-high temperature, approximately 400°F. Thread marinated chicken pieces evenly onto skewers, leaving slight space between pieces for even cooking.
04 - Place skewers on preheated grill surface. Cook for 12-15 minutes total, rotating every 3-4 minutes to ensure even searing on all sides. Chicken is done when internal temperature reaches 165°F and surface shows light charring.
05 - Spread prepared hummus generously across serving platter. Arrange grilled chicken skewers atop hummus bed. Sprinkle with fresh chopped parsley and accompany with lemon wedges, pita bread, and fresh vegetable accompaniments if desired.
