There's no "real" recipe for these, it's just a hodgepodge of veggies and fruits. However, I have learned that I like the veggies to be liquefied, so I generally add them first with about 2 - 4 cups of water and blend. Then I add my fruits and other ingredients. Blend again. (I love the liquefy button!) I like to drink mine with a straw especially when I'm adding more greens and removing some fruit.
Here are the foods I've used in my green smoothies (not all at the same time... different combinations each day):
Mustard Greens (don't like)
Fruits (fresh or frozen)
raspberries/blackberries (don't like because the seeds never really go away)
Milled Flax Seed
Wheat germ (very little... I don't like the taste)
Frozen orange concentrate
Cinnamon (just a little... too much will numb your tongue... trust me.)
Vanilla Soy/Rice Milk
Basically anything will do. Fruits and veggies don't have a chance to go bad around here anymore!
I haven't tried a savory green smoothie yet (garlic, onion, other veggies, no fruit).
