Chicken thighs marinated in a spiced yogurt, then simmered into a rich tomato and almond sauce.
This one's already gluten free as written. Chicken, yogurt, spices and stock are all naturally GF, just check the label if you're using a stock cube, as some brands use wheat as a thickener.
Leave the chicken to marinate overnight in the fridge if you've got the time, it makes a real difference.
Frozen pre-crushed garlic and ginger cubes save a load of effort here and melt straight into the hot oil, no chopping needed.
