Wash and take out the seeds of the tomato and the red pepper. Peel the onion.
Use a food processor to cut to small pieces the onion, tomato and the red pepper.
Then place a wire colander over a pot and pour this tomato/pepper/onion mixture into it. Press the mixture down with the back of a wooden spoon or a ladle or your palm to take out the excess water.
Then in a mixing bowl add the meat, all the spices and this tomato/pepper/onion mixture and start kneading. You need to knead about 30 minutes. The longer the better.
Rest the kebab dough in the fridge for half an hour.
Then get a bowl of clean water handy and start shaping. Take a handfull of the mixture in your hand. Turn it into a small orange sized ball. Wet the wooden stick and stick it into this ball. Turn the meat around to go downwards the stick to get a kebab shape. You might need to wet your hand while doing this, as the meat might stick in your hand or you might need to use the water to mend any cracks.
When you are finished with the kebab shaping cook in a preheated oven at 220 degrees using the grilling function. Turn side when one side is done.
The kebab will be cooked pretty quickly - in around 20 minutes you will be ready to serve.
