This is a great way of keeping greens to hand.. I noticed that my spinach kept getting slimmy before I had a chance to use it.. So, blending it with a little filtered water then freezing it into ice cubes to add to smoothies later is a perfect solution. 1 big bag makes 4 trays of spinach cubes. I put 1 tray into a zip lock bag and use that in 1 green drink.. You can do this with all greens, gonna do some Kale cubes later today!
