Place all the ingredients, except the ice, in a blender.
Once it starts to liquefy, add about 6 or 7 ice cubes – adjust to your desire – and blend until all the ice cubes are crushed and the peanut butter is completely blended.
Voilà! You have yourself a nutritious and delicious smoothie that is either great as a meal itself or maybe a snack to curb that afternoon hunger.
