How do you properly parboil vegetables before incorporating them into a stir-fry dish?

To properly parboil vegetables for a stir-fry dish, first bring a pot of water to a boil. Add the vegetables and cook for a few minutes until they are slightly tender but still crisp. Drain the vegetables and immediately transfer them to a bowl of ice water to stop the cooking process. Pat them dry before adding them to the stir-fry dish.
