I recently found this recipe from Dr. Oz (ala the Oprah Show).
1 bunch parsley
1 head celery
2 cups spinach
1/2 inch peeled ginger
2 cups cucumber or 1 medium cucumber
Do you have any favorite green smoothie recipes? I like sweet, and will probably add juice of some kind (orange, pineapple, etc) to help even things out a bit for me.
