Diagonally slice the green onions into pieces about 1 inch long and 1/4 inch thick. Set aside. Mix the oyster sauce, fish sauce, and water. Set aside. Heat a wok, add both kinds of oil, and swirl them over the surface of the pan. Stif-fry the garlic until it is light golden. Add the tofu, chiles, and bean sprouts.

Stif over high heat until all the ingredients are heated through and the mixture is boiling. Put the mixture in a serving bowl and sprinkle with pepper. Serve immediately or keep it warm while you prepare other dishes. Serve with Lime Sauce and rice. Source: Thai Home-Cooking from Kamolmal's Kitchen
