Soak the wooden skewers in water for 30 minutes to prevent them from burning on the grill.

Cut the chicken breasts into 1-inch cubes for even cooking.

Combine the olive oil, kosher salt, black pepper, and melted cowboy butter in a bowl.

Toss the chicken cubes in the marinade until they are well-coated.

Thread the marinated chicken cubes onto the soaked skewers.

Grill the skewers over medium-high heat for about 10-12 minutes, turning occasionally until the chicken is cooked through.

Serve garnished with fresh parsley.
