I at one point got dehydrated premade stuff but decided to go more with ingredients that cook easily and quickly, such as rice and lentils and some spices and dehydrated vegetables. You can get dehydrated kidney beans and lentils that cook very quickly,
but even regular dried lentils can be boiled in not very much time. Then you can control the salt content, taste and texture and get almost complete protein, and its just as easy to make as the fully prepared ones, and cheaper.
