01 - Whisk together olive oil, lemon juice, garlic, oregano, paprika, salt, and black pepper in a large bowl until thoroughly combined.
02 - Add chicken pieces to the bowl and toss to coat evenly with marinade. Cover and refrigerate for at least 20 minutes, or up to 2 hours for enhanced flavor.
03 - Heat grill to medium-high temperature, approximately 400°F.
04 - Thread chicken and vegetables onto skewers in an alternating pattern, creating colorful and balanced portions. Leave slight space between pieces for even cooking.
05 - Lightly brush assembled kabobs with any leftover marinade from the bowl.
06 - Place kabobs on preheated grill and cook for 12 to 15 minutes, rotating every 3 to 4 minutes, until chicken reaches internal temperature of 165°F and vegetables show light charring.
07 - Remove kabobs from grill and let rest for 2 minutes. Garnish with chopped fresh parsley and accompany with lemon wedges.
