Prepare a medium heat braai. Place the pork neck chunks and Braai Sauce in a sealable bag or plastic container. Toss well to coat the pork evenly, then leave to marinate for at least 20 minutes, or up to 2 hours in the fridge for a deeper flavour.
Cut the onions into eight wedges and the peppers into 5 cm squares.
Thread the skewers, alternating between the pork, wedges of onion and peppers.
Braai the skewers over medium coals for 15-20 minutes, turning every 3-4 minutes to ensure even cooking and a light char. The pork should be cooked through, and the vegetables slightly blistered.
Remove from the heat and allow the skewers to rest for 5 minutes before serving.
