Time management tip: to save time, start heating up water for the next step.
Tear off the amount of napa cabbage (3 oz) that you'd like to use, and place it in a large bowl or basin of clean water to wash. Tear off the larger outer leaves of the bok choy (3 oz) and add both the leaves and the rest of the bok choy to the water. Add the king oyster mushroom (3 oz) to wash it as well.
Peel the carrot (2 oz), cut the amount that you'd like to use, then add it to the bowl to wash. Wash the snow peas (1 oz) (or green beans if you can't find snow peas) as well. When the vegetables are clean to your satisfaction, set them aside to drain.
Cut vegetables
Ideally, all the vegetables will end up approximately the same, small size. This will help them cook evenly and also make the eating experience more convenient!
Cut the napa cabbage into small pieces, about half in inch thick.
Cut the king oyster mushroom in half lengthwise, then cut into small pieces.
Cut the carrot in half lengthwise, then into slices.
You can choose to leave your snow peas or green beans whole, or cut them in half at an angle.
Cut the bok choy open, then cut apart at the stem. For bigger individual leaves, cut them into small pieces at an angle.
