Do you find most smoothies to be too sweet for your taste? If so, then you’ll love this one. It’s as slimmed-down as can be, in both calories and sweetness. The banana binds the almond milk and greens; without something creamy they would separate and create an unappealing texture. This is a great smoothie to highlight a particular herb or spice. Try cinnamon, which can help stabilize your blood sugar, or turmeric and ginger to fight inflammation.
