How can I make an Überfood? Each day, you're supposed to get a certain number of servings of grains, vegetables, fats, etc. You know, the food pyramid.

However, instead of going to all the trouble to prepare three meals with several courses each and every day, I'd like to just have the same thing to eat, all the time. I'm hoping this isn't considered sacrilege for this site!

What I'm describing is an Überfood, as it has a near-perfect balance of all of the daily intake requirements. They make it for cats, dogs, and other mammals, so I'm sure it's possible for us primates. Like cats and dogs, I'd of course have the occasional treat, but it would always be above-and-beyond and not part of my daily nutrients.

What considerations should I put into making an Überfood?  Ideally, it would be shelf-stable and not need refridgeration. Texture and taste are less important.

Clearly, I don't know much about cooking or food preparation... But I think there's a better way than just buying an industrial blender, throwing a bunch of vitamins, vegetables, protien, etc., and seeing what turns up.
Sounds like you want Nutraloaf.  If you search google you will undoubtedly find recipes for this abomination.  It is designed to meet nutritional needs while minimizing the need for utensils.  You did say taste and texture weren't important.
