We've been making these smoothies for years now. It's such a refreshing way to get a wide variety of nutrients. Trader Joe's is a great place to stock up on frozen fruit. Strawberry and mango are our favorites, but we also sometimes add blueberry, raspberry, or pineapple. We think bananas are a must-add to any fruit smoothie, and kefir is a great probiotic and protein boost. I also tend to add a lot of flaxseed to our smoothies since it mixes right in and you can't even tell it's there.
Frozen mango chunks
1-2 bananas (great way to use up overripe ones)
Kefir (we like strawberry flavored)
Simply mix all ingredients well in a blender. Enjoy!
Play around with different fruit combos and see what you like the best.
