In a small bowl, make the sauce by combining the oyster sauce, soy sauce, honey, mirin, rice vinegar, and sesame oil, then stirring in the garlic and ginger.

Add a small splash of veg oil to a large nonstick pan on medium-high heat. Add the meat and fry until brown, about 5 minutes. If the meat gives off a lot of water or oil, drain the excess liquid. Add the broccoli and baby corn as well as a pinch of salt and a few grinds of black pepper, and continue frying for 2 to 3 minutes, until the veg are softened but still crunchy.

Add the sauce and white parts of the green onions to the pan. Stir to combine, then pour in the chicken stock. Bring to a simmer. Make a slurry by mixing the cornstarch with a few tbsp cold water, and add it to the pan. Stir until the sauce thickens slightly, about 2 minutes.

Cook the rice stick noodles according to the package instructions. Drain well, then add them to the pan and toss to combine. Garnish with a sprinkle of sesame seeds and the green parts of the green onions when serving.
