Remove the skin of the chicken then then cut into bite-sized chunks. Put these into a bowl and add the oil and spices. Marinate for about 30 minutes.
Meanwhile soak 8 wooden skewers in water. Cut the peppers and into bite-sized slices. Peel the onion, cut into 8 wedges.
Heat your BBQ, grill or griddle pan.
Thread the chicken, pepper and onion pieces alternating onto the skewers. Brush the onion and pepper with the marinade then season with salt & pepper.
Cook for 10-15 minutes, turning every couple of minutes. Be careful not to burn them - but they should be slightly charred and the chicken must be cooked through properly!
Drizzle with lime juice just before serving.
