Prepare the berbere chicken by sprinkling the spice mix and some salt on the chicken. Mix very well with a wooden spoon and keep to one side while you prepare the other ingredients.
Fry the onion in the oil until it translucent.
Pour in the chicken slices and allow to cook on both sides to seal the spices in.
Add chopped tomatoes, pasta and some water.
Add the berbere spice and some salt to taste. Give it a stir and cover the pan.
Allow to cook for the time specified on the pasta pack or until the pasta is cooked.
Just before it is ready, add the vegetables and cover for a few minutes.
