01 - In a large mixing bowl, whisk together olive oil, minced garlic, grated Parmesan, lemon juice, dried Italian herbs, salt, black pepper, and crushed red pepper flakes until combined.
02 - Add the chicken cubes to the marinade and toss thoroughly to coat. Cover the bowl and refrigerate for a minimum of 30 minutes, or up to 2 hours for enhanced flavor infusion.
03 - Preheat grill to medium-high heat. If using wooden skewers, soak them in water for 20 minutes to prevent burning during grilling.
04 - Thread the marinated chicken pieces onto skewers, allowing a small space between each piece for even heat distribution.
05 - Place the skewers on the preheated grill. Cook for 5 to 7 minutes per side, or until the chicken is thoroughly cooked and lightly charred.
06 - Remove the skewers from the grill and arrange on a serving platter. Garnish with chopped parsley and extra grated Parmesan. Serve with lemon wedges on the side.
