01 - In a large mixing bowl, whisk together olive oil, minced garlic, grated Parmesan cheese, lemon juice, dried Italian herbs, salt, black pepper, and red pepper flakes until fully combined.
02 - Add chicken cubes to the marinade and toss thoroughly to coat. Cover the bowl and refrigerate for at least 30 minutes, or up to 2 hours for enhanced flavor.
03 - Preheat grill to medium-high heat. If using wooden skewers, soak them in water for 20 minutes to prevent burning.
04 - Thread marinated chicken cubes onto skewers, spacing each piece slightly apart for even cooking.
05 - Grill skewers for 5 to 7 minutes per side, turning as needed, until the chicken is fully cooked and lightly charred.
06 - Remove skewers from grill and transfer to a serving platter. Sprinkle with chopped parsley and additional Parmesan cheese. Serve immediately with lemon wedges on the side.
