I love a good blueberry smoothie - the color, the sweet flavor, and the refreshing way they make me feel. Blueberries are my favorite berry in smoothies. They blend the creamiest, and do not have any seeds like other berries - so they are not tart. This makes blueberries easy to pair with bitter ingredients - like kale and walnuts in this smoothie. I have found that a fruit smoothie alone is not enough to satisfy me - especially if the smoothie is my meal. Thus protein (walnuts), and lots of veggies (zucchini and kale) have become a staple for my smoothies. Throwing some extra walnuts and hemp seeds on this smoothie really tops it off. It ads texture, and extra sustenance to get me through the rest of my day. A couple quick tips before giving this recipe a go: 1) I strongly suggest using raw, unsalted walnuts in this smoothie, as they will blend to a creamier texture and be a bit less bitter, toasted and unsalted will work though. 2) Freeze very ripe (as in brown or extremely spotted) bananas. These bananas are the sweetest and will be the creamiest in your smoothie as well! Simply peel your bananas, break into chunks and freeze in a bag until ready to use. I hope you all love this smoothie as much as I do! If you give it a try, be sure to let me know what you think!
