Toast the salt flakes in a hot pan until they start to brown - it's very important to do this to get the true salt and pepper flavour.
Mix the toasted salt and all the other spice mix ingredients together.
Sprinkle the chicken thighs with a couple of teaspoons of the spice mix.
Place them on a baking tray and cook as per pack instructions (usually around 30 minutes at 190°C).
When the chicken is cooked, heat up a wok sprayed with some low calorie cooking spray.
Add the spring onions, onions, chilli and peppers to the wok and cook until they start to brown slightly.
Add the chicken thighs to the wok along with 1 or 2 tablespoons of spice mix. Don't add it all at once, add it a bit at a time, taste and stop when it's spicy enough.
Cook through for another 3 or 4 minutes, then serve sprinkled with some finely chopped spring onions.
