Preheat the oven to 240°C/Fan 220°C/Gas 9. Line a baking tray with baking paper.
Put the chicken thighs into a mixing bowl, add the other ingredients with a generous amount of salt and pepper and turn the chicken to coat well in the mixture, preferably using your hands. You can marinate the chicken up to 48 hours in advance, or freeze the marinated raw chicken for use at a later date or for batch cooking.
Lay the chicken thighs on the lined tray and roast for 40 minutes or until sticky and charred around the edges and cooked through.
To serve, slice the chicken and serve in warmed flatbreads with Greek yogurt, coriander leaves, sliced spring onions and alongside lemon wedges for squeezing over.
