frozen strawberries, blueberries, banana, plain Greek yogurt, spinach (easily blends right in unnoticed - trust me!), and enough orange juice to make it blend well together. Note - if you don't use any frozen fruit, you'll need to add ice.
Then the bottom fell out. Literally. I didn't screw something together right in the blender and I made the biggest mess ever. Harper thought it was hilarious. Me? Not so much. That was not fun to clean up.
The kids loved them! Right down to the last drop. :)
