Heat the oil in a griddle pan. Season the chicken and chargrill in the hot pan for 5-6 minutes on each side. Transfer to the oven and cook for 10-12 minutes, until cooked through.
For the noodle cake, mix the noodles and sesame oil in a large bowl. Heat the vegetable oil in a small pan or blini pan and place the noodles in. Cook for 3-4 minutes on each side until crispy and golden.
To make the dressing, heat the vinegar, chilli flakes, sugar, soy sauce and garlic in a small pan for 4-5 minutes, stirring occasionally.
To serve, transfer the chicken to a serving plate. Serve the crispy noodle cake alongside and drizzle the dressing over.
