Do You Smoothie?

I am thinking of replacing at least one meal a day with a healthy smoothie, such as a Green Smoothie, which incorporates both veggies and fruit.

I've found a few yummy recipes online, but was wondering if maybe you have a few yummy but healthy smoothie recipes, too?

Oh, hey, you know what I found out? The casein in yogurt destroys some of the healthy stuff if added to a smoothie! I forget the exact details, mainly because I have a 19-month old power kicking my stomach right now, but Google it!!
