my smoothie recipe comes from the website "Oh She Glows"...
2 cups spinach, microwaved for 2 min to wilt (blends better this way)
1 scoop EAS whey protein powder
1 cup frozen fruit (I really love blueberries)
1 banana
2 tbs ground flax seed
1/2 cup soy milk, or whatever it take to get it blended.

wilting the spinach really makes it pretty much liquefy once you blend it, and between the banana, protein powder and berries, I don't taste it at all.

It keeps me full until about noon if I eat it at 7:30. Of course, I have to force myself to eat breakfast instead of just drinking coffee most days (even if I don't eat, I still get hungry for lunch at about the same time), but I've learned the hard way (bonked rides) that I have to start fueling early.
