What you'll need:
Simple Green Smoothie
1 - 3 c. spinach (depending on your taste buds)
1/2 c. frozen fruit (I use 6 frozen strawberries in this instructable)
1 32 oz. mason jar
Water (or orange juice)
Advanced Green Smoothie
To give your smoothie a little more nutritional pizazz, you can add just about any supplement. Here are some of my favorites:
1 Tbsp ground flax seed
1 Tbsp ground sesame seed
1 Tbsp hemp seed
1 scoop green powder (mmmm...chlorophyll...)
Step 1: Find a jar that works for your blender
I have had a lot of success with re-using Classico pasta sauce jars, but you can use canning jars, too.
Step 2: Fill your jar with the ingredients!
Once you've added your fruit and spinach, add some water (about 1 cup -- more for a juicier smoothie, and less for a thicker, shake-like smoothie. Experiment to create the texture that you like the best).
Note: If you are just beginning to venture into the world of green smoothies, you'll want about 2/3rds fruit, 1/3 greens. You might also want to substitute orange juice for the water. Work your way up to more greens, less juice, and more water. As you become accostomed to the taste, you can dilute the juice and add more greens.
Note #2: I packed the spinach in a little too much in that last picture. I ended up having to blend it in two stages. Oops.
