Wash the sprout tops, picking off any baby sprouts (you can add them later). Discard any tough outer leaves before pulling away the inner leaves. Peel ginger and cut into fine strips. Heat the oil then add the ginger until it starts to brown, then add the garlic followed by the wet sprout leaves (and tiny sprouts if any). Keep stirring until they begin to wilt (within a minute). Mix in soy sauce and serve immediately.
