When children tend to refuse healthy foods, then a smoothie is a great way to soften these boundaries a little. A green smoothie, which contains avocado, kiwi, banana, and a bit of peppermint, is a real energy bomb that is full of nutrients and vitamins. Avocado adds healthy fats and a creamy texture to this smoothie, while kiwi and banana provide freshness and sweetness. Peppermint brings a fresh twist that makes every sip enjoyable.
