<human>:  How do I make a healthy smoothie?
<bot>: Firstly, gather your ingredients. You will need fresh or frozen fruit, milk or a milk substitute, a liquid like water or juice, and any other add-ins you would like. Blend your ingredients together until smooth and enjoy! For a more nutritious smoothie, add ingredients like avocado, yogurt, spinach, flaxseed, or nut butter. You can also add nut milk, chia seeds, and other superfoods for added nutrition.
