Christa, GS stands for Green Smoothie. Part of my challenge this month was to add a green smoothie to my eating habits each day. I love it. It makes it so easy to get plenty of fruits and vegetables each day, and in such a yummy fashion! So far my favorite is frozen cherries, frozen bananas, spinach, and a splash of milk. Tastes like ice cream. :) Strawberry is also great, and I really enjoy orange/banana/spinach as well. Apple/cabbage isn't my favorite because the texture is a little funny, although it does taste good.
The kids usually have some too, and the green color doesn't bother them at all. :)
