Here it is:
1/2 Avocado (Haas is the best tasting)
1/2 English Cucumber (the skinny longs ones without seeds)
3 limes or 4 Limes (without the rind)
2 cups of Spinach (enough to fill the blender almost to the top)
1 tsp of Stevia (natural cactus sugar)
Several Ice Cubes to make it nice and cold to enjoy!
The mix it well in a blender!
