Yeah, I goofed by listing them in the heatless category. You can short-term store them without a fridge, though.
Obviously none of the things I listed will form a complete diet, but if you are eating mostly take-out they are probably a superior substitute for some fraction of those take-out meals.
Whether that's true or not depends where you live. The US and Europe have developed different systems for egg production and storage.
