A friend just got a Vitamix blender and is looking for smoothie recipes. He got a post about Joe Rogan's Green Smoothie Recipe that I thought I'd share with you 'cause it sounds pretty good. He has a YouTube video that you can Google - the sound quality isn't really good and it's not PG.
4 stalks kale
4 celery stems
1 cucumber
1 pear
1/2″ ginger
8 oz water (optional, to help items blend together more smoothly)
Blend the items together in a heavy duty blender.
