<human>:  What is the healthiest way for me to cook vegetables?
<bot>: The healthiest way to cook vegetables is to steam, bake, stir-fry, or roast them. Steaming or baking vegetables helps to retain the most nutrients, while stir-frying or roasting adds extra flavor. When roasting vegetables, it's important to remember to add a minimal amount of oil or butter for flavor. Whichever way you decide to cook the vegetables, be sure to not overcook them to maintain the most nutritional value.
