Place chicken, soy sauce, marinade & stir fry sauce and mirin in a large zip lock bag. Seal and leave to marinate in the refrigerator for at least 20 minutes.
To assemble the skewers, thread the chicken, mushrooms and spring onions onto the soaked skewers, alternating ingredients.
Heat a grill plate on medium heat. Spray skewers with the oil and grill for 3-4 minutes on each side or until the chicken has cooked through.
To serve place skewers and limes on a serving platter.
