Heat a heavy based pan over a medium heat and spritz with low calorie cooking spray. Add the onions and garlic and fry for 2 minutes.
Add the peppers and fry for a further 3 minutes.
Add the chicken, Spicentice, and lemon juice, stir well, and cook for 2 minutes.
Pour in the tinned tomatoes and hot water, stir well, and bring to a simmer.
Cook for a further 25 minutes, or until the chicken is cooked through and the curry has reduced to the desired consistency. Make sure that you stir often.
Serve, sprinkled with the fresh coriander, and enjoy!
