Heat a little bit of vegetable oil in a pan.
Fry chilli peppers in oil for about 30 seconds and then take them out of the pan and set them aside. See notes.
Fry onions and garlic for about 1 minute and then add the mushrooms.
Add salt and white pepper and fry for a further 4-6 minutes.
Make a quick slurry by mixing 1 teaspoon of cornstarch with 2 tablespoons of water, a few drops of sesame oil, and 1 teaspoon of soy sauce.
Add slurry to the mushrooms and then cook for about a minute.
Add garlic chives, stir for a few seconds and then turn off the heat.
Serve warm.
