01 - Combine olive oil, lemon juice, minced garlic, cumin, smoked paprika, oregano, salt, and black pepper in a large bowl. Add chicken cubes and toss to coat evenly. Marinate for at least 20 minutes, or up to 2 hours refrigerated for enhanced flavor.
02 - Blend chickpeas, tahini, lemon juice, olive oil, garlic, cumin, and salt in a food processor until completely smooth. Add water one tablespoon at a time until you achieve a creamy, spreadable consistency. Taste and adjust seasoning as needed.
03 - Preheat grill or grill pan to medium-high heat, approximately 400°F.
04 - Thread marinated chicken pieces onto skewers, leaving a small space between pieces for even cooking.
05 - Grill chicken skewers for 12-15 minutes, turning every 3-4 minutes, until fully cooked through (internal temperature reaches 165°F) and lightly charred on all sides.
06 - Spread hummus generously across a serving platter. Arrange grilled chicken skewers on top of the hummus. Garnish with chopped fresh parsley and serve immediately with lemon wedges, warm pita bread, and fresh vegetables if desired.
