This dish can be easily doubled, but like most stir-fry recipes, I don't recommend making more than two servings at once. A crowded pan will not allow you to get the intense heat and quick cooking time that is ideal. Once the first ingredient goes into the pan, it should take about 6 minutes to finish the dish. (Too much longer and you risk ending up with mushy vegetables or noodles.) In the photos above, I used Chinese broccoli but regular broccoli would work just fine.
