1 large banana
150g frozen berries
150g low-fat natural yogurt
1. Cut up the banana and put into a blender along with the berries (there is no need to thaw them beforehand)
2. Add the yogurt and milk and blend for 15-20 seconds until all mixed together and a deep lilac colour. Serve immediately.
I would recommend sieving after blending too as you still get little bits of berry and banana that don't totally break down and I hate drinks with lumps! X Bo
