Combine everything in the blender, and process until smooth.
If it is too thin, add a little more ice, and re-blend. If it is too thick, add a little more pineapple juice.
If it seems a little bland, add a spoonful of orange juice concentrate. You can't mess this up. :)
Notes
This smoothie makes yummy popsicles! Make a batch up just for that or use up your leftovers.
Try freezing the banana beforehand for extra creaminess.
There are lots of pineapple juice combinations that would be delicious in place of straight pineapple juice in this smoothie.
This smoothie would be especially easy to prep the night before! Measure the juices into a container to leave in the refrigerator, set out the banana, and measure out a container of ice for the freezer. In the morning, all you have to do is dump it into the blender jar!
