When I take smoothies to work, I tend to also grab some carrots and/or nuts on my way out the door to make sure that I'm getting enough energy for the work day. Consider what your body needs and what will keep it happy, healthy, and functioning the way it should based on your work (or play!) environment.
Cranberry Raspberry-Lemonade Smoothie
2 tablespoons frozen raspberry-lemonade concentrate
1/2 -3/4 cup frozen cranberries (I like more, but they are too tart for some people)
1 cup milk or milk alternative of your choice (I use plain almond milk)
1 tablespoon vanilla protein powder
Combine all ingredients in a blender and puree until smooth. Serve.
