who needs a recipe for a smoothy? just bung in a load of fruit and add whatever you fancy/have to hand. mine sometimes include all, some or none of the following: banana, oats, flax seeds, peanut butter, ground almonds, fresh ginger, ground coriander, plain yoghurt, almond milk, a teaspoon of cocoa powder, the crumbly bits from the bottom of a box of weetabix minis...
