The marinated tofu here is deceptively easy. Pricking the tofu all over with a fork lets the marinade seep in to leave an intense flavour. I like to blanch Asian greens then plunge them into cold water to refresh. This way, when they are tossed in the wok, they will remain a wonderful bright colour and retain their crunchy texture. Served with rice, this is a meal on its own or can be added to an array of other Chinese dishes in a banquet.
