4. Build & freeze smoothie kits

Prepping fruits and vegetables for a future smoothie may seem like some pretty advanced planning, but that's the beauty of it: smoothie kits will last FOREVER in your freezer. (Not literally forever, but they will last a long time.) When you're ready to whir up a smoothie all you have to do is dump your kit in the blender, add a few spoonfuls of nut butter, a splash of liquid, maybe some spices or sweetener, and flip the switch. Congrats—you just became a smoothie person.
