My kids and I love fruit shakes. They are cold and yummy. This shake has lots of vitamin C, anti-oxidants and good bacteria (from yogurt).
1 cup blackberries
1 banana, peeled
1 cup plain yogurt
1/2 cup berry juice
Add the above to blender and whirr until completely mixed. If you don’t like the seeds from the blackberries, use blueberries or raspberries instead.
