Place the chicken thigh fillets on a board. Mix together 2 tablespoons of the cornflour with the salt and pepper and sprinkle it on both sides of the chicken thighs.
Heat the sesame and neutral oil in a large frying pan (skillet) over a medium-high heat.
Add the chicken thighs and fry for 6-7 minutes, turning once, until golden.
Meanwhile, mix together the soy sauce, lime juice, honey, brown sugar, garlic, chillies and remaining 1 tablespoon of cornflour in a small bowl.
Once the chicken is golden brown, pour the mixture all over the chicken thighs, in the pan. Bring to the boil, then simmer for 5 minutes, until the sauce has thickened.
Top the chicken with sesame seeds, chilli flakes, lime slices and sliced spring onions, then serve.
