Tell me what to put in a smoothie.

Response:
A smoothie is primarily made up of fruit or vegetables, liquid, and toppings. The fruit can be frozen or fresh, and good options are bananas, strawberries, blueberries, and raspberries. To add some health benefits, you can also add vegetables like spinach. Adding liquid gives the smoothie a more drinkable consistency, and you can use either water, milk, or milk alternatives. Greek yogurt also adds protein. Finally, for toppings, you can add chia seeds or flaxseeds to give your smoothie some crunch.
