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. Let marinate for at least 20 minutes or refrigerate for up to 2 hours for deeper flavor penetration.
02 - Combine chickpeas, tahini, lemon juice, olive oil, garlic, cumin, and salt in a food processor. Blend until completely smooth, adding water one tablespoon at a time until you achieve a creamy, spreadable consistency. Taste and adjust seasoning as necessary.
03 - Heat your grill or grill pan to medium-high temperature, approximately 375-400°F.
04 - Thread the marinated chicken pieces onto skewers, leaving slight space between pieces for even cooking.
05 - Place skewers on the preheated grill and cook for 12-15 minutes, turning every 3-4 minutes, until chicken reaches an internal temperature of 165°F and develops light char marks.
06 - Spread the prepared hummus generously across a serving platter. Arrange grilled chicken skewers over the hummus. Garnish with chopped fresh parsley and serve alongside lemon wedges, pita bread, and fresh vegetables if desired.
