Sometime, a beautiful purple, green or yellow smoothie is not going to do the job! So, back in the days of taking my son to rugby, I embarked on a fairly long journey to convince a then pre-teen Rugby mad son that I could make him a healthy, nutritious and energy boosting shake he would be proud to take to rugby training. The aim of the game was to avoid him bowing down to the peer pressure of gulping a fluorescent blue or orange energy drink! Today, I can happily report that this shake is fab for my own post workout refuel too.
