Bok choy with plum sauce

• 1 pound bok choy
• 2 tablespoons peanut oil
• 1-2 tablespoons plum sauce

Trim the bok choy, removing any discolored leaves and damaged stems. Tear into manageable pieces. Heat a wok until hot, add the oil and swirl it around. Add the bok choy and stir-fry for 2-3 minutes, until the greens have wilted a little. Add the plum sauce and continue to stir-fry for a few seconds more, until the greens are cooked but still slightly crisp. Serve immediately. Serves 3-4
