We love making green smoothies. I have the best blender...it even grinds my wheat!! It's a blendtec just in case you were wondering. :) This little boy can't get enough of green smoothies he will do 3 cup fulls until he is satisfied. We just throw in about 2-3 cups of spinach, then we fill the rest of the blender up with frozen strawberries (from Costco, they have the best) and then we put in about a cup of apple juice. All my kiddos love them.
