Kale is a superfood, and it’s really popular. It’s also perfect for green smoothies. I’ve been making smoothies for a while now. I didn’t think my kids would love kale smoothies – no matter how healthy it was – until this recipe. This tastes delicious, refreshing and minty. The banana adds sweetness. It’s packed with calcium, vitamin A, vitamin C, and potassium – just to name a few.
