This is the soylent stuff, right? I dunno man, ever since I've seen the "soup" eaten on the Matrix, I said to myself to never just go full meals on juice. There's just something about being able to chew and enjoy your food (as well as the variety). I get it, it has everything the body needs, but tasting the way we want it? surely there's no harm in adding that (most of the time).

EDIT: That being said, I've had a ton of fun preparing oat meal in various ways (sweet, savory, wtf, etc.)
