There is no strict rule to what goes in a gado-gado, but it must at least include boiled eggs and boiled potatoes to count as one. The rest of the ingredients is really up to you. Some of the more common ingredients include: blanched cabbage, blanched bean sprouts, blanched snake beans, blanched green beans, blanched spinach, raw cucumber, boiled chayote, deep fried tofu, deep fried tempeh, and emping (melinjo crackers).
