I am into instant gratification.

I used to do smoothies on my 55 mile commute to school, and coffee on the 55 mile commute home. Car food. Now I do 'em because most of the time it's just an easier way to eat breakfast.

My smoothies (give or take)

1/2 block tofu
1 bananananana
1 big blob of plain yogurt
1 handful of frozen fruit or jam (scoop the jam, not handful)
Juice, soymilk, ricemilk, or cow milk as needed to make runny

Sometimes this makes enough for b'fast and lunch/snack. It also makes great frozen popsicle-things for the small creatures in your home.
