This is my very best winter pick-me-up recipe because sometimes I want full on nutrition with taste and this is packed with folic acid, potassium, magnesium and fibre:
1 large banana
3 squeezed oranges
300 ml or 1 big glass of buttermilk (use Kefir or even yogurt if you like)
1 spoon full of wheat-germ
Put it all in a blender with a few ice-cubes and serve chilled.
