I need some good smoothie recipes for this summer - my DS will start swim practice at 6:30 a.m. and needs to eat before he goes but is not interested in solid food at that hour. Any suggestions? He loves berries and just about any other fruit but is not really into bananas (unless the taste is hidden). Nothing too complicated, please - I have to make this at around 5:30 a.m. and who knows what my brain capacity will be at that hour! TIA!
