Yeah! Green smoothies are awesome, power packed nutrition! I'd love to share with you! This is my tried and true recipe, nothing fancy, I'm a basic girl

:
Organic baby carrots
romaine lettuce and/or kale (if you use baby spinach it gives it a wonderful emerald green look)
1 frozen banana (makes it creamy)
half a mango (really makes it creamy!)
sometimes I put some berries like raspberries (whatever's at hand, warning blueberries will give it a dark look instead of an green look)
bottled water
and I mix it all in my Blendtec blender using #4 button which blends it super smooth and the mango in it gives it a delightful flavour and so creamy smooth!
Note with this combo if I don't put enough greens in it (though it doesn't take much) the fruits and carrots will give it a paler green look, not so appetizing but still wonderful.
What have you tried so far?
