Cut the chicken breasts lengthways into 1-2 cm thick strips. Place each strip of chicken on a slice of bacon and skewer in a wave shape. Sprinkle with BBQ rub and press lightly.
Preheat the grill to medium temperature.
Grill the skewers for 2-3 minutes, turn, and grill for another 2-3 minutes. Then move the skewers to an indirect heat area and continue grilling at 200-220°C (390-430°F) for 15-20 minutes until the chicken reaches 74°C (165°F) internally.
