Turn on an air circulation on (not grill/broiler) oven to 175° C and set the rack to the middle position.
Place all the ingredients except of the chicken into a food processor’s bowl with the meatal blade attached. Work for couple of minutes until a saucy paste is created.
An hour before cooking the chicken fillets take them out of the refrigerator and place them in a roasting pan and rub the paste all over them. Cover with plastic wrap allow to come to room temperature for an hour. Take the wrap off and cook for 45’. Check for doneness with an internal thermometer aiming for a temperature of 77 degrees C.
For the noodles sauce we use a small saucepan placed on low heat and add all the rice vinegar along with the smashed lemongrass stalks, the chilli pepper, golden sugar and kaffir limes. Bring to a boil, and immediately remove from the heat, cover with a lid and allow for the flavours to come be infused for 10’. Then add the sesame oil and the hoisin sauce stir and keep aside.
In the meantime, bring a large pot filled with water to a boil and add the noodles. Cook according to package instructions, remove from the heat and keep aside in a bowl filled with water.
Place a large wok on high heat and add the rapeseed oil. Let it heat-up and toss in the garlic, ginger and the green parts of the scallions. Sauté for less than a minute and add the mushrooms. Keep on sauteing on high fire for about 2’ and then add the carrots and the bell peppers. Sauté for 2’ more and add the bean sprouts with the cabbage. Toss well and then add the cooked noodles along with the noodles sauce. Toss well to combine and remove from the heat.
To serve we place the noodles to a bowl, add some coriander and the green parts of the scallions. Garnish with a bit of Furikake seasoning and place on top slices of the cooked chicken.
