Preheat the oven to 200°C / 180°C fan / gas mark 6.
Mix all the kofta ingredients in a large bowl using clean hands and combine it all together to form a ball.
Form your koftas into small sausage shapes and thread onto the skewers. Note if you are using wooden skewers they will need soaking for 10 minutes. Place two koftas onto each skewer. You should have 6 skewers in total.
Lay the koftas over the top of a baking dish so the skewers are resting on each side and the meat is in between. Place in the oven for 15 minutes.
While your koftas are cooking, make your salsa.
In a saucepan heat a small amount of oil, then cook the onions and chillies for about 3 minutes.
Add the chopped tomatoes, coriander, sugar, salt and pepper then give it good stir. Place the lid on and turn down the heat to the minimum. Leave for 10 minutes or until the tomatoes are soft.
Cut your avocado into cubes and heat your red kidney beans on the hob for about 3 minutes.
To plate your taco, place two koftas in the centre of the taco by sliding them off the skewer. Add a spoon full of beans, avocado, salsa, yogurt and finish with some fresh coriander. Serve and enjoy!
