In a mixing bowl, whisk together ranch dressing, parmesan cheese, olive oil, minced garlic, parsley, black pepper, garlic powder, and lemon juice until well combined.

Place cubed chicken into a resealable plastic bag or shallow dish. Pour marinade over chicken, ensuring all pieces are well-coated. Seal and refrigerate for at least 30 minutes or up to 2 hours.

If using wooden skewers, soak them in water for 15 minutes to prevent burning.

Thread marinated chicken cubes onto skewers, leaving a little space between each piece for even cooking.

Preheat grill to medium-high heat (around 400°F).

Place skewers on grill and cook for 10-15 minutes, turning every 3-4 minutes, until chicken reaches an internal temperature of 165°F and has a nice char on the outside.

Remove skewers from grill and let rest for 3-5 minutes before serving.

Garnish with additional chopped parsley or extra parmesan cheese if desired. Serve with your favorite side dishes or dipping sauce.
