Clean the chilli pepper, cut lengthwise, remove seeds, wash and dice very finely. Wash the herbs and shake dry. Pluck rosemary needles and thyme leaves from the twigs and chop. Peel garlic and chop finely.
Mix everything in a bowl with some pepper.
Wash the chicken fillets, dab dry and spread with mustard. Salt lightly and sprinkle generously with the seasoning mixture on both sides. Mix soy sauce and honey.
Heat the oil in an ovenproof pan. Brown the chicken fillets on each side. Fry in a hot oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3) for approx. 10 minutes.
Remove the pan from the oven and add the soy sauce-honey mixture to the pan. Turn the chicken fillets in it and serve immediately.
