I mix

1 Banana
3 tablespoons of mixed seeds (flaxseed, pumpkinseed, sunflowerseeds, sesame)
3 tablespoons of oat bran
1 cup of berries (raspberry, blueberry, strawberry...)
1 cup of soy milk
(+water)

for a breakfast-smoothie almost every day. I got my Chia-seeds today maybe I'll add them in. Sometimes when it's very cold I cook some oatmeal and add blueberries and soy milk
