This is a great banana smoothie with a little bit of citrus in the form of lemon and orange to give it some bight.
I skipped the vanilla extract and added a good dollop of vanilla Greek yogurt, since I like the creaminess that brings to a smoothie. Used a frozen banana and added crushed ice, since we prefer a consistency a little on the thick side. Particularly like the addition of the fresh lemon and orange juices in this smoothie. Very refreshing. - 12 Mar 2015 (Review from Allrecipes UK & Ireland)
