What pairs well with smoothies, or are they meant to be eaten on their own?

When i have a smoothie i usually have a peanut butter sandwich, and it depends on what u put in a smoothie if u put in lots of sugar then it wont make it healthy; the fruit that u add to it makes it a healthy beverage yes beverage a smoothie is a beverage.A smoothie depending on the size will get me through to either lunch or to dinner. hope this helps
