1/2 banana, peeled
1/3 cup of fresh or frozen pineapple
1 cup fresh or frozen kale or spinach
A handful of fresh mint leaves
1 cucumber
2 cups of water
Juice of one lime

If you have a powerful blender like a Vitamix, then place all the ingredients and process until smooth. If you don't own a powerful blender, blend the kale and water until smooth. Then, add the rest of the ingredients and blend until smooth.
