I recently came across the Bolthouse Farms Juices and other beverages in the store.  (They are found in the refridgerated fruit section of most grocery stores)  They have been such a hit with my kids.  I bought several of the different kinds, to include Green Goodness.  While my kids were drinking their "Green", I was reading the list of ingredients.  They were laughing hysterically, because they just couldn't believe what I was saying.  "Broccoli, spinach, barley grass, artichoke..."  Seriously, it is in there.  I don't know how they get it to taste so good, but they do.  It is like drinking...
