To keep things interesting, I thought I would get some inspiration from the blogosphere.
First up is a green smoothie that I have made before and absolutely loved. The name says it all, Caramel Apple Smoothie from Healthful pursuit. The dates help to give this smoothie its lovely, sweet caramel flavour and the frozen apple makes it quite refreshing. You will need a relatively powerful blender for this though.
As winter is citrus season I have a few limes on hand. This key lime pie smoothie looks delicious and will be a great way to use up my limes.
