The trick is... There is no set recipe! I seriously just use what I have. BUT I do have to say, we usually have spinach or kale around, and some sort of frozen fruit (cold green smoothies are ALWAYS better!)
So here is the basics:
*handful (or two) of some kind of greens... Spinach, lettuce, kale, collard greens, anything.
*about a cup of frozen fruits (we usually use a berry mix, mangos, blueberries, etc...
*any other fruit or veggie you have laying around that you think could taste good, such as lemon (yumm!!) or lime, bananas, oranges, peaches, sprouts, carrots, avocado (makes it really creamy), you get the picture. We tend to use the fruit that is about to be tossed, but not always.
*either juice or water... I use enough to cover the blades on the blender to kind of give it an easier time.
Some other additions to add something else to it: yogurt, cinnamon, vanilla, maple syrup, wheat germ, nuts, protein powder, oh, the possibilities are endless!
Another hint, if you have produce that is nearing its end, wash it and dry it, if necessary, then put it in a Baggie a pop it in the freezer. I do this a lot with my greens, when they are on sale or I just happen to buy too much or something.
Also, if you freeze avocados or bananas, peel them first...it will help when you take them out.
