Not a fan of banana? You can use avocado instead which makes it really creamy. It doesn't blend as well as banana though.
Use good quality zip lock freezer bags and then wash them and reuse them each time.
You can also store the ingredients in mason jars in the freezer. They do take up a lot more space though and we like bags because they lay flat in the freezer and can be stacked.
Flatten the smoothie bags and remove the air before zipping them up as they will take up less space in the freezer that way.
Make sure to label each smoothie bag so you know when it went in the freezer and how long it will be fresh for.
The amount of liquid you add to the blender will depend on how thick or thin you like your smoothie. Feel free to add more or less.
This recipes is to make 4 smoothie bags (2 adult servings per pack). Each bag will be enough for 4 smoothie loving kids to share.
