In a blender mix the milk, protein powder, and banana together. Blend until smooth. Divine into three servings.
Add the blackberries to one and blend until smooth. Add some ice cubes to thicken the mixture. Pour into a large glass.
Rinse the blender and mix another third with the spinach and ice cubes. Process until smooth and all the spinach is broken up. Pour this over a spoon and on to the top of the purple layer. You don’t want to two to mix.
Rinse the blender and add a few ice cubes and a touch of yellow food coloring if you want it more yellow. Blend and pour over a spoon over the green layer.
Enjoy your fun layered protein shake for breakfast or a lunch substitute. It does a great job of keeping me full.
