One day for lunch last week, I had a smoothie in lieu of an actual meal.  The caloric content of a smoothie easily makes it a decent meal replacement, despite many people using it as a meal add-on.  And the fact that it's a solid pint or more of thick liquid more than makes up for its lack of solidity.  I personally wouldn't mind if at some point in the future, we ate all our meals either through a straw or out of some sort of hands-free eating device like a feed bag. #food
