We are on Spring Break, so I have some extra leisurely time in the morning and I love making smoothies (experimenting with different fruits and veggies). Even though they don't take very long, I seem to always be crunched for time on school mornings to make a smoothie. Typically I will make them for an after school snack instead.
Frozen blue kale (from WholeFoods)
dollop of vanilla yogurt
no sweetener (mother nature takes care of that)
