Yaki Udon with Vegetable Gyoza

Mix the soy sauce, oyster sauce, mirin, maple syrup, rice vinegar and 1 tbsp of water in a small bowl and set aside. Heat a large wok (or frying pan) over a high heat.

Once the wok is smoking, add the oil, followed by the mushroom stir fry and salad onions; fry for 5 minutes. Meanwhile, put a large pan of water on to simmer.

Add the noodles and soy sauce mixture to the wok and toss together for 2-3 minutes until the noodles are heated through and coated in the sauce. Add the gyoza to the pan of water and simmer for 3 minutes, then drain. Serve the noodles and dumplings with a drizzle of the chilli oil.
