In a large mixing bowl, combine olive oil, minced garlic, hot sauce, red pepper flakes, parsley, paprika, garlic powder, onion powder, salt, and pepper. Add the chicken, ensuring each piece is well-coated in the marinade. Cover and refrigerate for at least 30 minutes.

Preheat your grill to medium-high heat, around 400°F (200°C). Clean and oil the grates before heating.

After marinating, thread the chicken onto skewers, leaving space between each piece. Alternate with colorful veggies if desired.

Place the skewers on the grill and cook for 15-20 minutes, turning every 5 minutes, until the internal temperature reaches 165°F (75°C).

In a saucepan over low heat, melt butter and stir in minced garlic, hot sauce, red pepper flakes, and parsley, cooking for 2-3 minutes until fragrant.

Once cooked, drizzle the garlic butter sauce over the skewers and sprinkle with grated Parmesan cheese. Serve hot.
