Don't knock it till you try it! Adding cannellini beans to your smoothie seems like a weird idea, but just like tofu, it adds a creamy consistency without any flavor. But what's really important is the amount of fiber it offers to keep you full and satisfied all morning long. Give this metabolism-boosting smoothie a try, and you'll wonder why you didn't start adding beans to your blender sooner. It also has a sprinkle of cinnamon for calorie-free flavor and to speed up your metabolism.
