Green Lemonade

So far I have used one or more greens including: spinach, kale, collards, Swiss chard, spring leaf mix, romaine, leaf lettuce always with a lime or a lemon or both, and if I don't have an apple, I have used a small amount of carrots, berries or grapes. It's okay without celery but it tastes better with celery. We started by drinking just about two ounces each. At first my family was not too sure about the color. Some concoctions are prettier than others. Now we all drink between 6 to 12 ounces. The day just goes better if we have "green lemonade" first thing in the morning.

Has anyone else tried other ingredients?
