Clean, wash and cut the peppers into bite-sized pieces. Peel onions and cut them into large slices. Wash the meat, dab dry and cut into large cubes.
Put the bell peppers, onions and chicken cubes alternately on the skewers. Place them on a baking tray lined with baking paper. Spray a little oil all around and season with salt and pepper. Bake in a preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 20 minutes.
Mix ketchup and curry. Drizzle the skewers with it and continue to fry for about 5 minutes. Rice tastes good with it.
