More Smoothies

I have been really getting into smoothie making now that I have my blender.  Typically I throw a banana, ice, some type of fruit, spinach, protein powder, and milk into the blender.  I've been noticing that it is pretty heavy on the banana taste, though.  Tonight at the grocery store I bought some ingredients to make some new smoothie recipes, chocolate peanut butter banana and spiced apple pie.  I also bought some awesome smoothie straws at Bed, Bath, and Beyond this weekend.  I'm looking for a glass smoothie straw, though, to be a little more Earth friendly.
