Cook the pasta as per the instructions on the packet. In a pestle and mortar, mix the cumin, coriander, chilli flakes, garlic salt and chilli powder until thoroughly combined.
The chicken should be sliced into strips. Spray a pan with Frylight and cook the chicken for 5 minutes. Add the spice mix and tomato puree and cook out for 3 minutes.
Add the sliced peppers and onions, along with 200mls of water and mix well. Leave to cook for 10 minutes until the chicken is cooked through and the peppers and onions have just started to soften.
Drain the pasta and combine with the chicken fajita mix. Serve with a dollop of fat free yoghurt, or your topping of choice!
