It is getting warm here, having a glass of mixed fruit smoothie is really refreshing. Cici got me a cook book few months ago, and I saw a couple of smoothie recipes in it. I am making different kind of smoothie every day, purely made from available fresh fruits and natural yogurt, some of them are just mix and match, not really following a recipe. I don't add any sugar in my smoothies because the sweetness from the fruit itself is good enough for me. You may add some honey if needed.
Here are 2 of my smoothies, just gather all the ingredients and blend it until smooth or leave some fruit chunks if desired. I will post some more later. Enjoy!
