To Make the Veggie ice cube, you'll need a bunch of kale(stems removed and discarded), a package of spinach, and 1 large avocado. Blanch the kale and spinach in a pot of boiling water until wilted, about 1 minute. Strain the leaves and put in a food processor with avocado; blend until smooth. Pour mixture into ice cube trays and freeze.
This recipe has evolved over the last five years. I work out every morning and drink this afterwards. I am now lactose intolerant and have to use Lactaid(R) milk and yogurt and whey isolate which I get from Whole Foods(R).
You can switch out the ingredients with your personal preference, however having yogurt in the smoothie is very important since I have found that if I don't have any the smoothie separates into layers after a few minutes. The yogurt keeps everything suspended in place.
I use a Oster(R) Classic beehive blender with a blender bottle that fits on it. I have used it for a few years and blends frozen fruit great as long as you change the blades once in a while. My kids also love this recipe and it gets them to eat good greens that they wouldn't otherwise be interested in.
