Michelle, over at Oh Mishka, put up an awesome smoothie recipe the other day that I just had to try!! You can make it any way you like, but here's what I do:
3/4 cup orange juice
3/4 cup soy milk
2 handfuls of baby spinach
1 handful of frozen blueberries
Start with a clean blender (this should go without saying).
Add orange juice and soy milk (I don't measure it - just pour in a bit of each). Add 2 handfuls of baby spinach (or whatever deep green leaves you have on hand). Blend this up until the leaves are unrecognizable.
Add fruit: banana, blueberries, whatever else you want. Blend again.
Pour into a glass and enjoy!
(I promise you can't taste the spinach.)
