Salt
1/4 cup sultanas
1 cup button mushrooms (optional)
2/3 cup yoghurt (Greek full fat)
1 handful of chopped coriander

Method

Fry the onion in a little oil, adding the garlic after a minute. Then add the spices and stir in ad fry.
Add the chicken and mix with the spices to evenly coat.
Add tomato purée, cashews, mushrooms (if using) and sultanas - cover and cook for 5 minutes or until the chicken is cooked through and mushrooms slightly soft.
Uncover and add the yoghurt and chopped coriander - stir in well and then transfer to a serving dish.
