Blend all the ingredients together. Using frozen fruit gives it a creamy, smooth texture that is perfect for smoothies.
Instead of using frozen fruit, you could add ice or just ditch the whole frozen part of the recipe.
I freeze cut up banana after buying it at the shop.
All you have to do is peel it, cut it into smaller pieces, and place the pieces on top of a sheet of wax paper (I place ours on a baking sheet with a sheet of wax paper).
Freeze it for several hours or overnight, then place the banana pieces in a freezer bag and place the bag back into the freezer.
Now you have pre-frozen bananas for the next time you want to make a smoothie!
