These grilled chicken skewers are marinated in a blend of herbs and spices, then grilled to perfection and served with a zesty chimichurri sauce. To make the marinade, simply combine garlic, cilantro, parsley, oregano, red pepper flakes, salt, and olive oil in a food processor. Pulse until smooth, then pour over the chicken and let it marinate for at least 30 minutes. Thread the chicken onto skewers and grill for 10-12 minutes, turning occasionally, until cooked through. Serve with the chimichurri sauce on the side for dipping.
