Ingredients
2x125ml fruit-flavoured yoghurt, ideally strawberry, raspberry or cherry
400g/14oz fresh or frozen summer berries
290ml/½ pint cranberry juice
2 bananas, peeled and roughly chopped

Method
1. Place all of the ingredients in a liquidizer and blitz until smooth. Pour into tall glasses and enjoy straight away. If you want your smoothie on the move, pour it into a clean 'take-away' coffee cup with a lid and drink it through a straw. If you're fussy about pips or seeds or you're worried they'll get stuck in your teeth, strain the smoothie through a sieve before pouring into glasses.

WARNING: Frozen berries are very loud when being blitzed and are guaranteed to wake up the entire household as well as yourself.
