Step 1
To a wok set over high heat, add the oil and swirl to coat. When smoking, add the garlic and fry until fragrant, about 10 seconds, followed by the snow peas, snap peas, and chiles. Cook, stirring continuously, until the pods are bright green and beginning to brown, about 2 minutes. Stir in the pea shoots and 1 tablespoon of water and cook until wilted, 30–45 seconds. Add the oyster sauce, fish sauce, soy sauce, sugar, and 2 tablespoons water and cook, stirring continuously, until the peas and greens are tender and evenly coated with sauce, 1–2 minutes more.
