My Protein Shake (Banana and Walnut Smoothy)

This is the smoothie I have after every run or workout (I've never felt that the expensive professional shakes out there actually work), the banana gives you the carbohydrate you need to replenish your energy levels and the walnuts give you the protein hit you need to repair your muscles.

To make this smoothie all you'll need is:

4x bananas
1x large handful of walnuts
1-2x cups of almond milk (almond milk makes this smoothie deliciously creamy compared to using water).
