Heat the vegetable oil in a wok over high heat. Drop the garlic slices into the wok just as the oil begins to smoke. Stir the garlic around for about 30 seconds and add all the pea shoots into the wok. The water on the pea shoots from rinsing should be sufficient to keep the wok moist as the vegetable cooks. Add salt and stir-fry for about one more minute. The vegetable is ready when the leaves are just wilted. Plate and serve.
