Heat the oven to 180c. Arrange the nuggets on a baking tray and bake for 10 minutes. Remove from the oven and cut each nugget into 3-4 bite sized pieces.
Heat a wok or large frying pan over a medium-high heat. Add the oil and swirl around the pan. Add the sliced onion and stir-fry for 30-40 seconds. Add the heated nuggets. Add the chopped garlic in oil and mix well once more. Season with the salt & pepper seasoning and mix well. Add the spring onion and chilli flakes and mix again. Add the rice wine, mix once more and serve.
