01 -  In a large mixing bowl, whisk together olive oil, grated Parmesan cheese, minced garlic, lemon juice, dried Italian herbs, salt, and black pepper until well combined. 
 02 -  Add chicken cubes to the marinade, and toss thoroughly to coat each piece. Cover the bowl and refrigerate for at least 30 minutes, or up to 2 hours for optimal flavor absorption. 
 03 -  Set grill to medium-high heat, or preheat broiler if cooking indoors. 
 04 -  Thread marinated chicken, red and yellow bell peppers, and red onion alternately onto metal or soaked wooden skewers. 
 05 -  Place skewers on the grill and cook for 12 to 15 minutes, turning occasionally, until chicken is fully cooked and vegetables are lightly charred. 
 06 -  Remove kabobs from grill, sprinkle with chopped parsley and additional Parmesan cheese. Serve immediately with fresh lemon wedges.
