The other night we made these amazing Peanut Butter & Banana Smoothies. (We were trying to copy one we'd just had a smoothie place in IL.) We used (reduced fat) peanut butter and (low fat) frozen yogurt (to pretend we were being healthy) and some bananas. 
They were SOOOOOO good that I broke out the margarita glasses (haven't been used in a while sadly) and Christian even got one!! (he drank from the little matching shot glass and was delighted until he spilled it all over.) Thought I'd include a pic to show you how much better his nose is looking!!!
If you get the chance to make some you won't be sorry!!! (I was against the whole peanut butter- banana combo until I tried one.) We're having a great time here at the beach!!!!xoxo,
