In a small bowl, mix butter with parsley, garlic, parmesan, salt, black pepper, and oregano.
To a bowl, add the chicken along with mustard, lemon pepper, paprika, Italian seasoning, salt, garlic powder, onion powder, and black pepper. Mix together well.
After marinating, thread the chicken pieces onto skewers. If using wooden skewers, make sure they have soaked in water for 30 minutes to prevent them from burning. I like to add about 6 to 7 pieces onto each skewer.
Add the skewers to the air fryer and air fry for about 6 to 8 minutes at 425°F. Rotate the skewers and air fry again for about 6 to 8 minutes so both sides are golden.
Then take it out of the air fryer and brush with garlic butter.
Serve warm with ranch!
