is this the recipe?
100 g (3.5oz) spinach (fresh)
40 g (1.4 oz) cucumber
30 g (1 oz) protein powder
240 mL almond milk (unsweetened)
Stevia or your preferred sweetener (to taste)
Place ingredients in a blender and blend on high until smooth.
Add extra almond milk and/or water until you get desired consistency.
Add cinnamon or matcha powder (optional).

If so, I think I'll stay with mine. I don't care for milk/almond milk and always worry about so much spinach everyday so I have different greens, like kale, spring mix, collards, spinach, etc...then I have a protein powder I like, add the collagen and some unfortified nutritional yeast, water and ice.
In the old days I also added avocado but now I have so much fat to lose I don't look to eat fat.
I'd like to find something more nutritious then water. Coconut water has sugar I think, unless I drain a coconut and I've not found any in my area.
ps - i love cucumber with lemon and water in the summer...very refreshing. Not sure of the benefits in a smoothie and will check that out. Maybe it would supply some nutrients I'm missing.
